	port before each operation.

	whether it existed previously interned or not.  This can be an
	issue with dynamically loaded code, since sysintern can be called
	at any time.

2001-07-02  Radey Shouman  <Shouman@ne.mediaone.net>

	* eval.c (force): Now works for zero or multiple values.

2001-06-27  Steve VanDevender  <stevev@hexadecimal.uoregon.edu>

	* gmalloc.c (check_block, check_frag_blocks): Conditioned on
	#ifdef DEBUG_GMALLOC.

2001-06-27  Radey Shouman  <Shouman@ne.mediaone.net>

	* sys.c (prinport): Print filename or pipe command, if available.

2001-06-23  Radey Shouman  <Shouman@ne.mediaone.net>

	* r4rstest.scm (test-numeric-predicates): Added tests for bignum
	to flonum comparisons.

	* scl.c (lessp, eqp, lmin, lmax): Make bignum to float
	comparisons transitive as required by R5RS.
	(scm_twos_power, scm_bigdblcomp): Support functions added.

	* eval.c (m_letstar1): Introduced to allow more sensible error
	messages for LET, LETREC.

2001-06-17  Aubrey Jaffer  <agj@alum.mit.edu>

	* posix.c (scm_getlogin): Added -- doesn't work on RH6.2.

	* Init5d4.scm (getlogin, login->home-directory): Added.
	(home-vicinity): Defined in terms of getlogin, etc.

2001-06-14  Radey Shouman  <Shouman@ne.mediaone.net>

	* subr.c (scm_bitfield): Made more efficient.

2001-06-10  Radey Shouman  <Shouman@ne.mediaone.net>

	* scl.c (integer-expt): For negative exponents, raise to a
	positive power first, then reciprocate.  This should almost always
	reduce roundoff error..  For INUMs, convert to floats before
	raising to the positive power, to avoid allocating bignums.

	(next-double-float): Takes two flonums, returns the next flonum
	from the first in the direction of the second.  Not sure whether
	this should stay.

2001-05-28  Aubrey Jaffer  <agj@alum.mit.edu>

	* r4rstest.scm (test-inexact): Added (test (atan 1) atan 1 1).

2001-05-23  Radey Shouman  <Shouman@ne.mediaone.net>

	* eval.c (ceval_1, ceval_1): Optimize LAMBDA expressions without
	rest arguments in function call position to LETs.  Introduce
	IM_FUNCALL spcsym for other non-variable reference expressions in
	function call position so they are not repeatedly expanded.

2001-05-16  Aubrey Jaffer  <agj@alum.mit.edu>

	* Makefile (pdf): Added targets.

2001-05-15  Radey Shouman  <Shouman@ne.mediaone.net>

	* Macro.scm: (macro:compile-syntax-rules): Generalized ellipsis
	quote from (... ...) to (... <pattern-or-template>).

	* sys.c: (free_storage): Zero loc_gc_hook since it will be freed,
	otherwise restart may fail.

2001-05-14  Steve VanDevender  <stevev@hexadecimal.uoregon.edu>

	* eval.c (scm_arity_check): Lacked explicit return value in the
	tcs_closures case.

2001-05-05  Aubrey Jaffer  <agj@alum.mit.edu>

	* Macro.scm (@pprint): Added.

2001-04-17  Radey Shouman  <Shouman@ne.mediaone.net>

	* eval.c (scm_eval_values): Now applies eval, so that
	values-context errors are caught for expressions entered in the
	repl.  Example bug: > (cons (values) '()) => (#<undefined>)

	(ceval_1): Primitive @EVAL does not copytree its argument.

	* Init5d4.scm (eval): Now defined in terms of @eval.

2001-04-16  Aubrey Jaffer  <agj@alum.mit.edu>

	* Makefile (all): make x.so after other components.
	(myscm): Removed target; use 'make all' instead.

2001-04-16  Radey Shouman  <Shouman@ne.mediaone.net>

	* scl.c (previous_dfloat, next_dfloat, dfloat_parts): Fixed
	for gradual underflow, as long as DBL_MIN_EXP is #defined.

	* repl.c scm.h Init5d4.scm
	* eval.c (ceval_1, apply, cvapply): Moved most of the work of
	applying a closure into ceval_1, by providing a syntax token
	IM_EVAL_FOR_APPLY.  CALL-WITH-VALUES is now a specfun, no special
	form or closure needed.

2001-04-13  Radey Shouman  <Shouman@ne.mediaone.net>

	* scl.c (dfloat_parts, make_dfloat, next_dfloat):
	(previous_dfloat): Implement DOUBLE-FLOAT-PARTS,
	MAKE-DOUBLE-FLOAT, NEXT-DOUBLE-FLOAT, PREVIOUS-DOUBLE-FLOAT.  Low
	level floating point functions.

2001-04-10  Radey Shouman  <Shouman@ne.mediaone.net>

	* subr.c (scm_copybit): No longer makes so many bignums.
	(scm_2scomp1): Static auxiliary function.
	(scm_big_ash): Uses scm_2scomp1.

2001-04-09  Radey Shouman  <Shouman@ne.mediaone.net>

	* subr.c (scm_big_ash, scm_ash): Faster bignum ash,
	allocates only one bignum per call.
	(scm_copy_big_2scomp): Static support routine.

2001-04-07  Radey Shouman  <Shouman@ne.mediaone.net>

	* repl.c (scm_stack_trace): Reworked with general stack-inspection
	function estk_frame.
	(def_err_response): Use null s_subr argument to indicate that an
	entire expression is being printed.

	* eval.c (macroexp1): Check early for unbound variable references
	in a form, so nicer error messages can be produced.

2001-04-06  Radey Shouman  <Shouman@ne.mediaone.net>

	* subr.c (scm_big_and): Fixed bug in LOGAND for one negative and
	one positive argument.
	Bug example: (logand #x-10000 #x3ffffffff) => #x3ffffffff

2001-04-04  Radey Shouman  <Shouman@ne.mediaone.net>

	* Macro.scm (macro:compile-syntax-rules): Better error messages,
	renamed some internal functions for clarity.  Fix checking of
	pattern variable rank in templates.  Some legal syntax-rules
	templates were being rejected, eg
	(syntax-rules () ((_ (?x ...) (?y ...))
	                  (let ((?x (list ?y ...)) ...)
	                    (list ?x ...)))))

2001-03-30  Radey Shouman  <Shouman@ne.mediaone.net>

	* eval.c (scm_values): Exported, since it can reasonably be called
	from subrs.

	* record.c (recprin1): Call default printer if the custom printer
	returns #F.  Print object-hash value of the rtd after type name,
	so all distinct record types can be distinguished by eye.

	(rec_rtdprin1): Custom printer for record type descriptors,
	includes rtd object-hash value.

2001-03-29  Radey Shouman  <Shouman@ne.mediaone.net>

	* repl.c (everr): Pass a `writing' value of 2, rather than
	1, during printing of error messages, so writing procedures
	may take special action.

	* record.c (recprin1, rec_prinset): record-printer now takes
	three arguments instead of two, the third being a boolean
	WRITING?.
	Supress calling the record-printer during error reports,
	avoiding the possibility of a recursive error.

	* eval.c (m_letrec1): Fix error report in case macro keyword
	is a synthetic identifier.
	(m_letstar): Preserve distinction between LET* and LET in the
	printed representation of evaluated code, for easier debugging of
	backtraces.

2001-03-24  Dai Inukai  <GAF05426@nifty.ne.jp>

	* scmmain.c (main): Since release 2.0.5, FreeBSD's double
	precision arithmetic defaults to 53 bits instead of 64 bits.  Set
	precision to 64 bits for all arithmetics and run the risk of
	overflow, though I have not seen any in 6 months of use.

2001-03-27  Radey Shouman  <Shouman@ne.mediaone.net>

	* Macexp.scm (macro:expand):
	* eval.c (scm_macroexpand1): Now expand identifier macros.

2001-03-26  Radey Shouman  <Shouman@ne.mediaone.net>

	* Macro.scm (syntax-rules): Only use procedure->identifier-macro
	if needed, so macros print something without an error message.

	* eval.c (scm_macroexpand1): Expand forms with identifier macros
	in keyword position (needed for macro:expand).  Should also expand
	single identifiers ...

2001-03-23  Radey Shouman  <Shouman@ne.mediaone.net>

	*sys.c (scm_gc_hook, scm_run_finalizers, mark_finalizers):
	Added hook to be run like an interrupt shortly after gc.  Added
	finalizer facility to gc.
	(scm_add_finalizer): Implements Scheme-level interface to
	finalizer facility, ADD-FINALIZER.

	*scm.c (process_signals): run scm_gc_hook.
	(setitimer): beautified somewhat.

	*repl.c (scm_top_level): Modified for gc hook.

2001-03-20  Radey Shouman  <Shouman@ne.mediaone.net>

	* eval.c (ceval_1): modified
	(values, m_call_wv, scm_eval_values): Added.
	Implement CALL-WITH-VALUES and VALUES by returning extra values in
	scm_env_tmp.
	(scm_arity_check): Raise an error for unknown tc7_specfuns.

	* repl.c (repl): Expects and prints multiple values.

	* Init5d4.scm (call-with-values): Implemented by wrapping
	undocumented special form @CALL-WITH-VALUES.  CALL-WITH-VALUES
	is hard to implement using the C level apply function, because
	that function is not tail-recursive.

2001-03-18  Aubrey Jaffer  <agj@alum.mit.edu>

	* build.scm (build): Removed unused parameter scm-srcdir.

	* scm.spec (%post): 'ln -s %{prefix}/lib/scm /usr/local/lib/scm'
	fixes vicinity problem caused by linking /usr/local/bin/scm.

Thu Mar 15 21:33:30 EST 2001  Aubrey Jaffer  <jaffer@aubrey.jaffer>

	* patchlvl.h (SCMVERSION): Bumped from 5d3 to 5d4.

2001-03-15  Aubrey Jaffer  <agj@alum.mit.edu>

	* x.c (init_x): Don't scm_ldprog("xatoms.scm") because it
	redefines STRING.

2001-03-15  Radey Shouman  <Shouman@ne.mediaone.net>

	* scm.spec: Added spec file to generate a .rpm file.

2001-03-13  Radey Shouman  <Shouman@ne.mediaone.net>

	* Macro.scm (macro:compile-syntax-rules): Support for identifier
	macros.

	* repl.c (iprin1): Print inlined procedure calls without infinite
	recursion.

	* scm.h: subtypes of tcs_cons_imcar are broken out for use in repl.c.

	* eval.c (makidmacro): Implement PROCEDURE->IDENTIFIER-MACRO.
	(macroexp1, lookupcar, prinmacro): Clean up macro type codes,
	support identifier macros.

	(m_inline_lambda, env_depth, env_tail, ceval_1): Support inline
	procedures.  Commented out for now, since the macro expander is not
	yet smart enough to figure out which lambda expressions can be
	inlined.

2001-03-04  Aubrey Jaffer  <agj@alum.mit.edu>

	* unif.c (init_unif): Removed scm_ldstr() call -- was failing to
	define string-case functions when compiled on files.posmikk.

	* Init5d3.scm (string-case): provided if string-upcase! defined.
	(display-file): Take optional port argument.

2001-02-25  Aubrey Jaffer  <agj@alum.mit.edu>

	* build.scm (build:serve): Improved error reporting.

2001-02-22  Radey Shouman  <Shouman@ne.mediaone.net>

2001-02-12  Aubrey Jaffer  <agj@alum.mit.edu>

	* Init5d3.scm (pprint): Added (returns last argument).

2001-02-07  Aubrey Jaffer  <agj@alum.mit.edu>

	* unif.c (init_unif): Moved string-*case definitions from
	Init5d3.scm.  Added string-append.

2001-01-30  Marc Espie  <espie@lusheeta.liafa.jussieu.fr>

	* build.scm, *.c: Ported to OpenBSD.

2001-01-21  Aubrey Jaffer  <agj@alum.mit.edu>

	* x.c (x_event_keysym): Added.  Translates XKeyEvent to KeySym.
	(x_window_geometry_set): Added interface to XConfigureWindow.

	* Makefile (keysymdef.scm): Added target.

	* inc2scm (scm<-includes): #ifdef each prospective #define.

2001-01-18  Radey Shouman  <Shouman@ne.mediaone.net>

	* ramap.c (ramap_cxr): Fix bug in dynamic allocation of
	workspace for large number of arguments (>= 5 in argument list).

2001-12-18  Aubrey Jaffer  <agj@alum.mit.edu>

	* Makefile (xafiles): Generated xlib-scheme files weren't being
	installed.

2001-01-18  Aubrey Jaffer  <agj@alum.mit.edu>

	* x.c (scm2display_screen): Fixed off-by-one problem.

2000-12-06  Aubrey Jaffer  <agj@alum.mit.edu>

	* r4rstest.scm (Section 5 2 1): added (begin)s.

2000-12-04  Radey Shouman  <Shouman@ne.mediaone.net>

	* eval.c (m_begin): now accepts (BEGIN) which evaluates to
	#<unspecified>.
	(m_expand_body): checks for memoized (BEGIN) so that empty BEGINs
	do not interrupt a sequence of internal definitions.  Properly
	rewrites internal definitions in several BEGINs as one LETREC,
	rather than several.

2000-11-13  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* x.c (x_default_ccc, x:default-ccc): Added.
	(x_list_properties, x:list-properties): Added.
	(x_window_ref, x:window-ref): Added.
	(tc16_xccc): Added.
	(CCC2SCM_P, CCC2SCM, xtc_ccc): Added backlinks from CCCs.

	(x:default-visual): Removed.

	* xtest.scm: Removed use of x:default-visual.

	* xgen.scm (xatoms): Added.

	* xatoms.scm: Translation of Xatom.h added.

2000-10-14  Aubrey Jaffer  <jaffer@ai.mit.edu>

	(call-with-input-file):
	(call-with-output-file): Use call-with-open-ports.

2000-10-07  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Init5d3.scm (call-with-outputs): Added.

2000-09-24  Jacob Strauss  <jastr@mit.edu>

	* scm.texi (waitpid): Fixed return value paragraph.

2000-09-23  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>

2000-09-09  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* r4rstest.scm (display): Test only on chars and strings.

2000-08-05  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* rautil.scm (subarray): Added.

2000-06-11  Ben Goetter <goetter@mazama.net>

	* build.scm (Microsoft-C-nt): Set options correctly for
	feature 'stack-limit.

	* scmfig.h (MSDOS): NT lacks sbrk().

	* patchlvl.h (SCMVERSION): Bumped from 5d2 to 5d3.

2000-06-01  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* scm.texi (Making SCM): Updated.

2000-05-02  C Nick Beaudrot <cbeaudro@cs.brown.edu>

	* scmfig.h: __SVR4 is the official Sun flag.

2000-04-18  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* r4rstest.scm (modulo): Added test cases.

2000-04-18  Radey Shouman  <Radey_Shouman@splashtech.com>

	* subr.c (modulo): Fixed sign handling bug for INUM0, following
	Dirk Herrmann's <D.Herrmann@tu-bs.de> fix for Guile.

2000-03-31  Radey Shouman  <Radey_Shouman@splashtech.com>

	* ioext.c (file_set_position): Do not disable port tracking for
	zero pos.

2000-03-30  Radey Shouman  <Radey_Shouman@splashtech.com>

	* ioext.c (file_set_position): For tracked ports (line & column
	number), issue warning and turn off tracking.

	* repl.c (scm_port_col): column numbers made consistently 1-based.
	Fixed handling of ungetted chars.

2000-03-28  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Makefile (Xlibscm_toc.html): fixed.

	* Transcen.scm (pi, pi*, pi/): Added.

2000-02-24  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Init5d2.scm (warn, error): Don't use PROVIDED?, it can cause
	error loops.
	(library-vicinity): Give a meaningful error message if we can't load
	require.scm.

2000-02-16  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Macexp.scm (macro:expand): Fixed for keywords that would be
	lexically shadowed except for hygiene.

2000-02-15  Radey Shouman  <Radey_Shouman@splashtech.com>

	* eval.c (ceval_1): Check for immediate procedure argument to
	APPLY.

2000-02-14  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Init5d2.scm (read:sharp): Accept #! syntax without checking
	line-number, so source files may be READ.  Made more robust.

	* Macexp.scm (macro:expand-syntax): Fixed handling of BEGIN with
	only one subform.

2000-02-11  Radey Shouman  <Radey_Shouman@splashtech.com>

	* eval.c (env2tree): Rewritten to make it easier to change

	* eval.c (makro): Abstracts process of making syntax.
	(makacro, makmacro, makmmacro): Now call makro.
	(makpmacro, @procedure->primitive-syntax): Scheme level way of
	defining primitive syntax, meaning syntax that @macroexpand and
	hence macro:expand will not expand.

	* scm.h (IM_DEFINE): now an ISYM but not SPCSYM, since IM_DEFINE
	no longer occurs in executable Scheme code there is no reason
	dispatching on it need be fast.  There is now one spare SPCSYM.

2000-02-06  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Macexp.scm (macro:expand): Fixed handling of CASE.

	* eval.c (m_letstar): Transforms (LET* () ...) into either a
	BEGIN, a single body form, or, if at top level, a LAMBDA
	expression.  Wrapping macro arguments in (LET () ... ) to allow
	internal DEFINE becomes free.

	(ceval_1): Code to deal with zero binding LET* commented out.

	(nullenv_p): Added, since we test for null environments in both
	m_define and m_letstar.

	(scm_extended_env, env2tree): #define constant
	ENV_TREED for the car bit that identifies environments that have
	been migrated out of ecache.

	(wrapenv): Return '() if at top level, instead of
	allocating a cell for an environment object.

	(topdenote_eq): Added to reduce code size.

	(m_begin): if only one form, just returns it.
	(scm_macroexpand1): Fixed to work with macro:expand.

2000-02-06  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Macexp.scm: Added, rewritten replacement for Macroexpand.scm.
	Implements MACRO:EXPAND including LET-SYNTAX and LETREC-SYNTAX.
	Rewrites synthetic identifiers to symbols for pretty display.

2000-02-04  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* build.scm (C-libraries): __FreeBSD__ uses libncurses.

	* crs.c: __FreeBSD__ includes ncurses.h

2000-02-02  Radey Shouman  <Radey_Shouman@splashtech.com>

	* scm.texi: Updated documentation for DEFMACRO and SYNTAX-RULES.

	* ramap.c (array_map, array_for_each, array_imap): No longer
	need to call procedurep, scm_arity_check is sufficient.

	* eval.c (scm_arity_check): Was not doing the right thing if
	passed an immediate as a procedure.

	(ceval_1): Added ALLOW_INTS_EGC to ensure that a tight
	loop applying a closure of >3 arguments will handle signals.  Bug
	report thanks to Tomas Lozano-Perez <tlp@mit.edu>.

2000-02-01  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Xlibscm.texi: TeX doesn't like @itemx in @tables.

2000-02-01  Radey Shouman  <Radey_Shouman@splashtech.com>

	matched in patterns as a literal ... ellipsis, allowing use of
	ellipses as syntax in user macros.

	* eval.c (scm_env_cons_tmp): Removed, replaced in one remaining
	use by scm_env_cons3.

2000-01-28  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Init5d2.scm (file-exists?, file-readable?): Zero errno to
	prevent spurious error messages.

	* Macro.scm (@print): Moved from Init*.scm, where it did no good
	since 'macro was never provided at that stage.

	(destructuring-bind): SYNTAX-RULES version, gives better error
	reporting.

2000-01-28  Dorai Sitaram <dorai@owlnet.rice.edu>
	(actually contributed March 1993)

	* Init5d2.scm (destructuring-bind):
	(defmacro:get-destructuring-bind-pairs): Added for destructuring
	DEFMACRO.

2000-01-28  Radey Shouman  <Radey_Shouman@splashtech.com>
	* Init5d2.scm (defmacro:simple-defmacro): Added, does what
	DEFMACRO used to do.
	(defmacro): Now does CL style destructuring.

2000-01-27  Radey Shouman  <Radey_Shouman@splashtech.com>

	* Init5d2.scm (defmacro): Now accepts
	(DEFMACRO (<name> . <args>) ...) as equivalent to
	(DEFMACRO <name> (<args>) ...)

2000-01-24  Radey Shouman  <Radey_Shouman@splashtech.com>

	* eval.c (map, for_each): Check that the cdr of each list
	argument is in fact a pair -- averting possible segfault.

2000-01-11  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Makefile (SCMLIT, SCMEXE): local executables for build, bench, ...

2000-01-09  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Init5d2.scm (track-all, stack-all, break-all): Added autoloads.

1999-12-23  Radey Shouman  <Radey_Shouman@splashtech.com>

	* repl.c (scm_top_level): Moved dowinds() call later in the error
	recovery sequence so that the errjmp_recursive flag is cleared
	before calling DYNAMIC-WIND exit thunks.  This move prevents
	spurious "recursive error" exits.
	Bug report by Tomas Lozano-Perez <tlp@ai.mit.edu>.

1999-12-17  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* scm.texi (Bibliography): Added (Japanese) SchemePrimer.

1999-08-20  Radey Shouman  <Radey_Shouman@splashtech.com>

	* repl.c (def_err_response): Error message for expand-time only
	environment.

	* eval.c (lookupcar, id_denote): Now handle environment objects
	in scm_env, lookupcar will complain if this happens in a run-time
	(rather than expand-time) context.

	(eval_syntax): Added, to be used in Macroexpand.scm for LET-SYNTAX,
	LETREC-SYNTAX.

	(ceval_1): Fixed bug in eval.

	frame may be pushed, that is, when some invocation of eval may
	modify the environment.  The bottom of the stack trace (the form

	* crs.c (lwinsch): Renamed from lwinsert.  Why were idlok and
	nodelay commented out?

1999-07-02  "Dai INUKAI(GAF05" <GAF05426@nifty.ne.jp>

	* rgx.c: __FreeBSD__ include should be "gnuregex.h".

	* Macro.scm (renaming-transformer): Now passes a memoizing RENAME
	procedure, so that renaming the same identifier results in renamed
	identifiers that are EQV?  per "Hygienic Macros Through Explicit
	Renaming".

	* Init5d0.scm (defconst): Now allows redefinitions without effect
	in the sense of EQUAL?  rather than EQV? to allow reloading code
	defining constant list structure.

	Burger & Dybvig
	"Printing Floating-Point Numbers Quickly and Accurately"
	<http://www.cs.indiana.edu/scheme-repository/doc.publications.html>
	But floating point rather than bignum arithmetic is used -- due to
	this state of sin one slop factor was introduced.  It would be
	good to check this on non-IEEE-754 architectures.

	(istr2flo): Now reads floating point numbers with exponents somewhat
	below -MAXEXP, since this such numbers can be represented with
	gradually underflowing denormals.

	that it becomes optional.

	* scm.c (run_scm): Deleted, subsumed by main().

	* patchlvl.h (INIT_FILE_NAME): #defined even for RTL case.  The

	* repl.c (def_err_response): Fixed to print stack trace even if
	err_exp is not defined.

	* repl.c
	* sys.c
	* scm.h errjmp_bad is now a pointer to a string, rather than an
	int, so that the final error message can say in which critical
	code section the error occured.

1998-12-03  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* repl.c (scm_top_level): renamed from repl_driver.

1998-12-03  Radey Shouman  <Radey_Shouman@splashtech.com>

	* scl.c (makdbl): Combined some DEFER_INTS and ALLOW_INTS,

	* setjump.h: windframe removed -- dowinds could only be processed
	while (possibly oversize) stack was intact.

	* scm.h (ARGn .. PROF_SIGNAL): Special err_pos values renumbered
	from 1; this allows 0 to indicate message has been printed.
	(dynwinds): restored to sys_protects.

	and restart(); dowinds() now done after longjump.
	(repl_driver): cur_inp being closed now indicates that SCM should
	exit -- after printing error messages.

	err_pos==0, don't print message.

	* Init5c4.scm (fluid-let): Shrunk using multi_set returns.

	* eval.c (scm_multi_set): Now returns new list of old values.

	after writing its character limit.  This makes it safe to print
	out possibly circular structures in error handling routines.
	(reset_safeport): Now returns non-zero only if its argument
	really was a safeport.

	* setjump.h (SAFEP_JMPBUF): Macro accessor for the jmp_buf,

	safeport.

	* repl.c (scm_stack_trace, def_err_response): Use new
	safeport features.

	* Macro.scm (substitute-in-template): Added check that all pattern

	printed.
	(err_head): More robust test for output to stderr, to
	decide whether to call perror or not.

	(reset_safeport): Now does exactly nothing if handed a
	non-safe-port.
	(init_types, init_storage): Moved initialization of tmp_errp and
	sys_protects earlier, in case allocating ptobs or smobs causes
	errors to be thrown.

1998-11-24  Radey Shouman  <Radey_Shouman@splashtech.com>

	* scm.h (NUM_IFLAGS): Added to make COOKIE, UNCOOK definitions a
	little easier to read.

	* sys.c (reset_safeport): Added, resets count and optionally

	mark function doesn't have to.
	* unif.c:

1998-08-17  Radey Shouman  <radey@colorage.com>

	* sys.c (scm_egc, scm_egc_copy_roots): Eliminated extra root

	LETREC, since internal DEFINE is now rewritten.

1998-08-10  Aubrey Jaffer  <jaffer@colorage.com>

	* sys.c (scm_fill_freelist): added.  Assures that at least
	MIN_GC_YIELD cells are in freelis.  This is used before returning
	from interrupts.

	* repl.c (handle_it): Discard 2 cells (because of CDR in NEWCELL).
	Call scm_fill_freelist();

1998-08-08  Aubrey Jaffer  <jaffer@ai.mit.edu>

	tickled by running Scheme code from interrupts.

	(scm_egc, scm_egc_copy_roots): Now take a single argument, a gc
	root.  Simplifies handling of the case where scm_egc calls igc,
	and possibly itself.

	* repl.c (growth_mon): Now prints "shrank" instead of "grew" if
	the relevant limit decreased.
	(handle_it): Do env cache gc before applying interrupt
	handler, to protect data on the estk, which might move.

Wed Jul 22 16:36:48 EDT 1998  Aubrey Jaffer  <jaffer@scm.colorage.net>

	* patchlvl.h (SCMVERSION): Bumped from 5c1 to 5c2.

1998-07-22  Radey Shouman  <radey@colorage.com>

	* sys.c: Added include of unistd.h for linux.
	(freeprint): Distinguishes between free cells (on freelist)
	and new cells.
	(scm_egc): Check for scm_estk, scm_estk_ptr not consistent.

	*scmfig.h (DEFER_INTS, ALLOW_INTS, DEFER_INTS_EGC):
	(ALLOW_INTS_EGC): ints_viol calls changed.

	* ramap.c (array_for_each, array_map): Always act as if CCLO is
	defined, this does no harm, and allows CCLO optimizations for the
	dynamicly loaded case.

	* posix.c: Added include of unistd.h for linux.

	* eval.c (ident2sym): Now available in Scheme as
	IDENTIFIER->SYMBOL.
	(closure): Removed env argument, now uses scm_env and is more careful

	* eval.c (ceval_1): Changed IM_SET to make High C happy.

	* scmfig.h: ioext.c: Added STDC_HEADERS #define and #include
	<unistd.h> for linux. Allows use of the rename() system call,
	which works for some filesystems that do not allow multiple links
	(smbfs).

1998-07-16  Aubrey Jaffer  <jaffer@colorage.com>

	* repl.c (repl): changed __TURBOC__ flag to __MSDOS__.  This
	enables the cr/lf fix for DJGPP also.
	(repl): Enabled cr/lf fix for __HIGHC__ also.

1998-07-16  Radey Shouman  <radey@colorage.com>

	* eval.c (lookupcar): Second argument now specifies what to check:
	LOOKUP_UNDEFP for error on undefined, LOOKUP_MACROP for error on
	keyword.  LOOKUP_UNDEFP and LOOKUP_MACROP are #defined only in
	eval.c.  Error is again signalled for undefined symbols at top
	level.

1998-07-14  Radey Shouman  <radey@colorage.com>

	* eval.c (ENV_PUSH, ENV_POP): Modified for interrupt safety.

	(ceval_1, apply, procedurep, macroexp1, make_specfun):

1998-07-09  Radey Shouman  <radey@colorage.com>

	* eval.c (ceval_1): Modifications to allow rewriting of interal
	DEFINE to LETREC: If an ISYM is evaluated in non-tail position the
	body of which it is the CAR is macro expanded by m_expand_body,
	which rewrites internal DEFINE.

	(m_expand_body): Added.

	(m_macroexp1): Added argument to control error checking:
	m_expand_body may speculatively expand forms in the wrong
	environments.  Made argument number checks conditional on
	RECKLESS.

	(m_body): Added, error checks bodies and inserts the ISYM tokens.

	(m_lambda, m_letstar, m_letrec1, m_letrec, m_let): Now
	call m_body.

	(m_cond, m_case, m_quote): Modified to avoid destructively changing

	expands forms the process must be reversible.

	(m_ident_eqp): Fixed to use proper environment.

	(renamed_ident): Added DEFER_INTS_EGC.

	Added prototypes for static functions.

1998-07-07  Radey Shouman  <radey@colorage.com>

	made conditional on CAUTIOUS.

	(ceval_1, evalatomcar, lookupcar): Moved check for
	using macro as variable from ceval_1 and evalatomcar to lookupcar.

1998-07-02  Radey Shouman  <radey@colorage.com>

	* Init.scm (call-with-current-continuation): Now subr.

	* eval.c (ceval_1): Made CALL-WITH-CURRENT-CONTINUATION an inlined
	smob, like APPLY.  Flushed @CALL-WITH-CURRENT-CONTINUATION.

	ecache allocated lists now no longer passed to apply of asubrs and
	rpsubrs -- this is not interrupt safe.

	(macroexp1): Added argument number checks for subrs, this gives error
	messages with unmemoized code.

	* eval.c (ceval_1): Fixed error reporting -- "wrong number of
	args" was sometimes reported as "wrong type to apply".

	Now pass arglist allocated in ecache for asubrs and rpsubrs with
	3+ args.

1998-07-01  Radey Shouman  <radey@colorage.com>

	* eval.c (ceval, ceval_1, ilookup, lookupcar, farlookup):
	New model of interrupt control for protecting ecache references
	using DEFER_INTS_EGC, ALLOW_INTS_EGC.  These need not be strictly
	nested, ints are always allowed by ceval_1 before tail-calling a
	subr.
	(ceval_1): @apply flushed in favor of a smob denoting apply and
	understood by the evaluator -- allows ecache allocation of
	argument lists.
	(scm_macroexp1): Now checks arity for closures, checking had been
	broken for non-CAUTIOUS SCM.

	* scmfig.h (DEFER_INTS_EGC, ALLOW_INTS_EGC): Defined.

	* sys.c (scm_env_cons, scm_env_cons, scm_env_cons2):
	(scm_extend_env): DEFER_INTS replaced with DEFER_INTS_EGC.

	* repl.c (repl_report): At verbose level 3 now reports number of
	ecache cells migrated and why, also number of ecache garbage
	collections.
	(ints_viol): Reports filename and line number of violation, and
	filename and number of last previous DEFER/ALLOW_INTS.


1998-06-23  Radey Shouman  <radey@colorage.com>

1998-06-22  Radey Shouman  <radey@colorage.com>

	* eval.c (ENV_PUSH): Fixed problem introduced during last change:
	estk was overstepping its bounds.

1998-06-19  Radey Shouman  <radey@colorage.com>

	* eval.c (ilookup, farlookup, unmemocar, ceval_1):
	(id_denote): Wrapped all pointer-chasing of possible ecache cells
	in DEFER/ALLOW_INTS for safety when interrupt handlers may
	evaluate Scheme code asynchronously.

	(scm_macroexp1, m_define, m_atlet_syntax): Environments now
	always wrapped when passed to macro expanders.

	(ecache_p, debug_env_car, debug_env_cdr): Added for CAREFUL_INTS
	checking.

	(test_ints): Added when CAREFUL_INTS is defined for checking interrupt
	safety.

	* repl.c (ints_viol): Now prints file and line number.

1998-06-15  Radey Shouman  <radey@colorage.com>

	* scm.h (SCM_ENV_SAVE, SCM_ENV_RESTORE): Added, to prevent
	oversights in sys.c.

	* sys.c (scm_env_cons, scm_env_cons2): Made interrupt safe;
	return results in global scm_env_tmp, use DEFER/ALLOW_INTS.
	(scm_extend_env, scm_env_cons_tmp): Added.
	(scm_env_acons): Deleted, superseded by scm_extend_env.

	*eval.c (ceval_1, apply): Replaced and rewrote scm_env_ routines
	to use new interrupt safe versions.  ENV_TMP replaced by
	scm_env_tmp, it was hard to remember that ENV_TMP might move.
	CLEAR_ENV_TMP removed since scm_env_tmp will be overwritten almost
	every time estk is pushed.

1998-06-15  Aubrey Jaffer  <jaffer@colorage.com>

	* build.scm (compile-c-files *unknown*): Now uses
	BATCH:APPLY-CHOP-TO-FIT BATCH:TRY-SYSTEM rather than BATCH-SYSTEM.

	rebuild-catalog.
	(default-for-platform): new batch-dialect added.
	(guess-how): removed.  Guessing delayed using
	default-for-platform.

1998-05-28  Radey Shouman  <radey@colorage.com>

	* eval.c (ceval_1): setjmp changed to setjump.

	* continue.h:
	Changed setjump, longjump to use sigsetjmp, siglongjmp if it
	looks as though we're POSIX

1998-05-28  Aubrey Jaffer  <jaffer@colorage.com>

	* repl.c (handle_it): absorbed wta() call always used with it.
	(SIGALRM_deferred): renamed from alrm_deferred.
	(SIGINT_deferred): renamed from sig_deferred.
	(han_sig han_alarm): collapsed into (new) process_signals().

	* scm.c (alrm_signal int_signal): now call handle_it() directly,
	instead of through han_sig() and han_alarm().

	* scmfig.h (CHECK_INTS): simplified; deferred_proc when non-zero
	is address of procedure to call for signal processing (always
	process_signals()).

	* sys.c (sysintern mksubr): "const" added to declaration of first
	arguments.

1998-05-27  Aubrey Jaffer  <jaffer@colorage.com>

	* repl.c (everr): fixed really broken default vs. dowinds stuff.

	* socket.c (l_accept): moved DEFER_INTS so accept() call won't
	block.

1998-05-27  Radey Shouman  <radey@colorage.com>

	* repl.c: Fixed bug in scm_stack_trace: could have a negative
	number of stack frames if interrupted at top level.

1998-05-26  Aubrey Jaffer  <jaffer@colorage.com>

	* scmfig.h: Metaware __HIGHC__ lacks sbrk (LACK_SBRK).

1998-05-21  Radey Shouman  <radey@colorage.com>

	* sys.c (must_realloc): Fixed sense of check on realloc return
	value in must_realloc.

	* scmfig.h: Borland sbrk() is a noop.

	* sys.c: Fixed ECACHEP for Borland C.

	* Init.scm: Removed check for duplicate key values for CASEV (now
	done by CASE).

	* Init.scm (casev): Removed check for duplicate key values for
	CASEV (now done by CASE).

1998-05-21  radey  <radey@scm.colorage.net>

	* scm.texi: Documented changes to closure format.

	* sys.c: cosmetic changes.

Wed May 20 17:53:52 EDT 1998  Aubrey Jaffer  <jaffer@ai.mit.edu>

1998-05-20  Radey Shouman  <radey@colorage.com>

	* eval.c: Added check for duplicate key values for CASE.

	* sys.c (scm_egc): Modified scm_egc to prevent a major gc from
	happening inside an ecache gc -- which was causing environment lossage.

	* Makefile: made check or checklit part of normal build.

	* scm.texi (Evaluation): Added description of FARLOC.
	(Memory Management for Environments): Added Tom Lord's
	documentation of ecache.

	* build.scm (build): compile-c-files linux: don't use -O2 when -g
	is specified.

1998-05-14  Radey Shouman  <radey@colorage.com>

	* Init.scm (bit-extract, logical:bit-field):
	(logical:bitwise-if, logical:copy-bit):
	(logical:copy-bit-field): definitions added for SLIB compatibility.

	* subr.c (scm_bitfield): renamed BIT-EXTRACT to BIT-FIELD,
	added range check on END.
	(scm_bitif, scm_copybitfield, scm_copybit): added.

1998-05-12  Aubrey Jaffer  <jaffer@colorage.com>

	* eval.c (m_case): Added checks for ELSE clause.

	* Init.scm (defconst): added.
	(casev): added.
	(print-args): fixed (environment-cache broke).

	* eval.c (env2tree): exported to Scheme as environment->tree.

1998-05-11  Aubrey Jaffer  <jaffer@colorage.com>

	* continue.c (dynthrow): Giving up on HPUX stack growth.
	"growth[] being optimized out" message disabled for HPUX.

	* sys.c (try_open_file): Renamed from open_file.
	(open_file): Now calls back to Scheme; applies `open-file'.

Fri May 8 17:40:44 EDT 1998  Aubrey Jaffer  <jaffer@scm.colorage.net>

	* patchlvl.h (SCMVERSION): Bumped from 5b4 to 5b5.

1998-05-08  Radey Shouman  <radey@colorage.com>

	* eval.c (m_letrec1): added to support tagged environment frames.
	(m_let, m_letrec, m_lambda, m_do): Now put an ISPCSYM in the last
	cdr of the names they add to the environment, this is intended for
	debugging.

1998-05-07  Radey Shouman  <radey@colorage.com>

	* repl.c (scm_brk_report): Added.
	* scm.c (main): set global variables remembering initial brk.

	* eval.c (ceval_1): LETREC now adds extra (empty) environment
	frame so internal define does not upset memoization.
	* r4rstest.scm: tests for LETREC/internal DEFINE bug added.

1998-04-22    <radey@colorage.com>

	* repl.c (repl_driver): Added sbrk call just before dumping --
	fixes problems with linux dumped executables.

1998-04-16    <radey@colorage.com>

	* unif.c (scm_logaref, scm_logaset): Added.

Thu Apr 9 11:31:20 EDT 1998  Aubrey Jaffer  <jaffer@scm.colorage.net>

	* patchlvl.h (SCMVERSION): Bumped from 5b3 to 5b4.

1998-04-08  Aubrey Jaffer  <jaffer@colorage.com>

	* sys.c (gc_mark): first column #endif was within comment.
	(sweep_symhash): was being called by igc -- even with NO_SYM_GC flag.

1998-04-07  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* build.scm (link-c-program highc.31): added -stack 65000.

	* sys.c (gc_mark): added CHECK_STACK;

1998-04-06  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* sys.c (gc_mark): Checks strings and symbols for extra 0 byte.
	(mark_syms): Added check for extra 0 byte; check strhash() of
	symbol matches bucket index.

1998-04-06  Aubrey Jaffer  <jaffer@colorage.com>

	* unif.c (make_uve): Changed to call makstr for strings.  This is
	so extra byte will be 0.

	* time.c (your_time): PharLap.51 ftime() is non-monotonic.  Fix
	added to assure ftime() never decreases.

1998-04-03  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Init.scm (apply:nconc-to-last): Changed value to nconc2copy;
	this allows apply's definition to remain unchanged.

1998-04-03    <radey@colorage.com>

	* rope.c: scm_cell_p now returns true for env cache cells, so they
	may be printed during debugging.

1998-04-03  Ben Caradoc-Davies  <bmcd@physics.otago.ac.nz>

	* sys.c (gc_sweep): If a segment is freed during garbage
	collection, the heap size counter is adjusted, but the cells
	collected counter is not. Then when calculating cells allocated,
	cells in a freed segment are counted twice (negatively).

1998-04-03  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* scm.texi (Low Level Syntactic Hooks): Documented behavior of
	@apply; turning a former bug into a feature.

1998-04-01  Aubrey Jaffer  <jaffer@colorage.com>

	* scl.c (ex2in): changed tc7_cxr floident() to tc7_subr_1 ex2in()
	so it will handle complex numbers.

1998-04-01    <radey@colorage.com>

	* eval.c (nconc2copy): Added to fix bug in apply that
	allowed local SET! to mutate lists passed to APPLY.
	* Init.scm (apply): now uses apply:nconc-to-copy.

1998-03-26  Radey Shouman  <radey@colorage.com>

	* eval.c (ilookup, lookupcar, farlookup, ceval, evalatomcar):
	(ceval_1, iqq, wrapenv): Substantial changes to use
	copy-collected stack cache intended to reduce time in gc.

	* sys.c (egc_mark, egc_sweep, egc_copy, egc_copy_stack):
	(egc_copy_roots, scm_egc): The cache garbage collector.
	(scm_env_cons, scm_env_cons2, scm_env_acons): Functions to
	allocate storage in the environment cache.

	* repl.c (scm_egc_start, scm_egc_end, scm_ecache_report):
	(scm_stack_trace): Added to support environment cache.
	stack-trace now does not print all of stacktraces deeper than
	10 levels.

1998-03-20  Patrick Lecoanet  <lecoanet@cena.dgac.fr>

	* sys.c (igc): Use of NO_SYM_GC flag fixed.

1998-03-20  Aubrey Jaffer  <jaffer@colorage.com>

	* eval.c (m_define): "redefining built-in " message now
	conditional on verbose >= 2.
	(evalatomcar): unquoted vectors give warning when verbose >= 2.
	(EVALCELLCAR): Now always uses ATOMP, which catches all non-pair cells.

1998-03-20   Radey Shouman  <radey@colorage.com>

	* Macro.scm (macro:compile-syntax-rules): Allows vectors to
	be used as patterns and templates, per R5RS.
	* eval.c (unpaint): Unpaints identifiers in quoted vectors.

1998-03-09  Aubrey Jaffer  <jaffer@colorage.com>

	* repl.c (dump): made compatible with change to boot-tail
	* time.c:
	* scmfig.h: Removed support for HAVE_CONFIG_H.

1998-03-09   Radey Shouman  <radey@colorage.com>

	* time.c: I found that SCM on Linux uses ftime(), but that ftime()
	is implemented in glibc as a call to time().  Linux does support
	gettimeofday(), which does allow 10 msec resolution.  I tried
	using the definition of ftime() using gettimeofday() at the end of
	time.c (#ifdef freebsd).  It worked like a charm.

1998-03-05   Radey Shouman  <radey@colorage.com>

	* Init.scm (boot-tail): added `dumped?' argument.
	* Init.scm (set-vicinities!): added.
	* time.c (reset_time): Added to fix user time report for dumped
	executables -- now reports the time since invocation, rather than
	the time since dumping.
	* scm.c (init_scm): Calls reset_time if dumped.
	* scm.c (scm_find_impl): Wrapper for scm_find_impl_file.
	* scm.c	(find-init-file): added Scheme interface for scm_find_impl.

1998-02-27  Bob Schumaker <cobblers@netcom.com>

	* dynl.c: added Macintosh support.

1998-02-23  Drew Csillag <drew_csillag@geocities.com>

	* scm.c: Port for __CYGWIN32__

1998-02-17   Radey Shouman  <radey@colorage.com>

	* Macro.scm (macro:compile-syntax-rules): Fixed to recognize
	non-identifier literals in patterns.

1998-02-09  <amu@mit.edu>

	* scm.h (CGETUN):
	* sys.c (noop0): I found two places where SCM uses a possibly
	signed type for characters in a stream and risks confusing '\377'
	(a legitimate character) with EOF (-1).  This patch addresses this
	problem, and should make SCM's streams completely 8-bit clean.

1998-02-11  Aubrey Jaffer  <jaffer@colorage.com>

	* scm.texi (Index): combined indexes into one node.  Added use of
	@url command.

Mon Jan 12 10:12:20 1998  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* disarm.scm: (require 'disarm) disables opening and modifications
	of files.

Sun Jan 11 22:52:59 1998  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* posix.c: replaced C definitions of open-input-pipe and
	open-output-pipe with call to scm_ldstr().

Sat Jan 10 11:54:03 1998  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* Init.scm (read:eval-feature): moved into read:sharp (only use).
	(read:sharp): now handles `#\.'; moved from lreadr in "repl.c".

Sun Dec 21 19:40:31 1997  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* repl.c (exit_report exit_report): improved.
	* sys.c (stack_report): improved.

	* scl.c (iint2str): split into two routines.  Negative radix
	argument now forces unsigned conversion.

	* sys.c (alloc_some_heap): heap size variables were confused.
	heap_cells is now used instead of heap_size.

	* setjump.h (MIN_GC_YIELD NUM_HASH_BUCKETS): moved from scmfig.h.

	* scm.h (THRASH): added.

Mon, 01 Dec 1997 17:56:43 Andreas Menke  <asmenke@bln.de>

	* sys.c (must_malloc must_realloc): Bumps up mtrigger if less than
	1/8 of malloc space was reclaimed by GC.

Wed Dec 17 22:40:45 1997  Aaron Ucko <amu@mit.edu>

	* rgx.c (lregcomp): There is a small bug in rgx.c; a few things
	should be set before sending the pattern buffer to
	re_compile_pattern(). These fields should be set to zero, which
	means the bug only appers after memory is reused. This only
	affects use of GNU regex (i.e., only happens with _GNU_SOURCE
	defined). cf. regex.info for more information.

Wed Dec 17 22:40:45 1997  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* sys.c (free_storage): added fflush for stdout and stderr
	(because those ports don't get closed).

Sun Nov 30 23:21:05 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* build (build-from-argv): split from "build.scm" so that cgi
	scripts don't carry getopt baggage.

Thu Nov 20 09:45:28 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* build.scm (build): suppress-files field restored to C-libraries
	table.  It really is the correct way to deal with "findexec.c".

Sun Nov 16 13:43:21 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* mkimpcat.scm: 'hobbit, 'scmhob, and 'build added.

	* Link.scm (compile-file link-named-scm): Fixed.  Require of
	strings removed.  Tested with Hobbit 5x.
	(scm:object-suffix): changed to ".o"; only used by link-named-scm.

Sun Nov  2 23:15:57 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* patchlvl.h (SCMVERSION): Bumped from 5b2 to 5b3.

	* mkimpcat.scm: modified for new SLIB catalog arrangement.

Sat Nov  1 14:19:24 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* sys.c (gc_sweep): added `contin_bad' argument.  When set,
	gc_sweep will warn of any uncollected continuations of non-zero
	length.  This should make unexec problems less mysterious.

Tue Oct 28 16:54:00 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* Init.scm (home-vicinity): added.  Used to find "ScmInit.scm".

Sat Oct 25 23:05:43 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* unexsunos4.c: added from emacs.

	* unexhp9k800.c: added from emacs.  Broken -- doesn't change the
	segment sizes.

	* unexalpha.c: added from emacs.

Sat Oct 18 11:50:34 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* build.scm (build C-libraries): changed horrible `supress-files'
	field to `lib-support'.
	(rebuild-catalog): added.  Called by dll and dlls methods.

Sat Oct 11 23:19:55 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* scm.texi (Compiling and Linking Custom Files): Added to describe
	how to use "build.scm" with custom files.

Fri Oct 10 00:31:08 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* Makefile (myscm4 myscm5): now delete slibcat and implcat to keep
	them from getting stale.

	* gmalloc.c: HP-UX B.10.10 A doesn't have getpagesize.h.

Fri Oct 10 00:18:40 1997  Peter E. Davis  <pete@media.mit.edu>

	* unexhp9k800.c: added HP-UX unexec support.

Mon Sep 29 15:18:37 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* sys.c (mark_syms): No longer mark the value cell because value
	 cells get returned by calls to intern().  This caused a rare GC
	 leak which showed up in large programs.

Sun Sep 28 21:36:53 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* scm.h (const): defined to comment for hpux native cc.

Sun Sep 28 14:48:10 1997  Radey Shouman  <shouman@zianet.com>

	* ramap.c (array_imap): Fixed for zero-rank arrays arguments.

Fri Sep 19 23:23:46 EDT 1997  Aubrey Jaffer  <jaffer@ai.mit.edu>

	* patchlvl.h (SCMVERSION): Bumped from 5b1 to 5b2.

Fri Sep 19 23:17:48 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* build.scm (build:build): DEFAULT field-name changed to
	DEFAULTER in concert with SLIB/dbutil.scm.

Tue Aug 26 17:40:44 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* build.scm (build): Changed sun to sunos; This gives automatic
	platform from uname.

Wed Jul  2 14:25:52 1997  Anthony Green  <green@cygnus.com>

	* scmfig.h (FENCE): macro added.  DEFER_INTS/ALLOW_INTS doesn't
	actually promise to keep the critical code within the boundries of
	the DEFER/ALLOW_INTS instructions. It may very well schedule it
	outside of the magic defined in those macros.  GCC's volatile asm
	feature forms a barrier over which code is never moved.

Wed Jun 25 12:56:22 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* repl.c (tryload): Undid previous tail-recursive hack; it caused
	errors and warning to issue from grossly wrong line numbers.

Sun Jun  8 21:40:50 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* mkimpcat.scm: updated for shared-library wb.

Mon May 19 18:12:33 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* dynl.c (l_dyn_main_call): added for SUN_DL.

Sat May 17 23:21:05 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* repl.c (lreadparen): Now calls wta when EOF is encountered in
	list.  This must have broken when rewritten to use `UNDEFINED' as
	magic-cookie.

Sat May 10 21:54:47 EDT 1997  Aubrey Jaffer  <jaffer@scm.bertronics.com>

	* patchlvl.h (SCMVERSION): Bumped from 5b0 to 5b1.

Sat May 10 21:08:41 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* mkimpcat.scm: moved from Init.scm, macro feature now properly
	listed.

Thu Apr 17 15:16:56 1997  Denys Duchier  <Denys.Duchier@ps.uni-sb.de>

	* build.scm (build): extended with the new platform
	sun-svr4-gcc-sunld because my system runs solaris, uses gcc as its
	compiler, but is configured to use sun's linker rather than gnu's.

	I tested the changes in so far as the resulting system compiles,
	runs, passes the tests, and is able to dump an image which can be
	successfully restarted.  I used the following command to create my
	building script:

	build.scm -p sun-svr4-gcc-sunld -o SCM+ -w redo \
	--compiler-options=-DHAVE_UNISTD_H -F bignums \
	arrays array-for-each inexact rev2-procedures \
	record compiled-closure generalized-c-arguments \
	i/o-extensions regex socket posix unix dump \
	cheap-continuations macro

	* scm.texi (Build Options): updated the documentation of `build
	options': removed memoize-local-bindings, which is not supported
	by build.scm, and added macro, which is.

	* ecrt0.c: modified the sparc's asm in ecrt0.c to call main
	and _exit when __svr4__ is defined instead of _main
	and __exit.  It seems the prepending of an underscore
	is a thing of the past.

Tue May  6 12:34:43 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* Init.scm (print-args): syntax added.

Mon Apr 28 20:24:47 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* mkimpcat.scm: created from "Link.scm"; mkimpcat.scm creates
	"implcat" in implementation-vicinity, supporting slib2b0
	catalog abstraction.

	* repl.c (dump): dump (defined by init_repl) now sets *catalog* to
	#f in order to trigger loading of "slibcat" and "implcat".

	* build.scm (build): make-nothing renamed to update-catalog.
	update-catalog and make-dll-archive create fresh "implcat".

	* sys.c (open_file): ALLOW_INTS was misplaced, causing lots of
	"ints already enabled" messages.

	* repl.c (ints_viol): written.

	* scmfig.h (DEFER_INTS ALLOW_INTS): rewritten using ints_viol() to
	allow easy gdb breakpointing.

	* repl.c (lreadpr): renamed from lreadr().  New lreadr() created.
	(flush_ws): fixed linum++ bug.
	(lreadparen): rewrote to use UNDEFINED as close-parenthesis magic
	cookie; #+foo <expression> can now appear at end of lists and files.

Fri Apr 25 22:52:20 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* scl.c (istr2flo): supplied missing IMP test before INEXP test.

Fri Mar 21 08:44:52 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* Transcen.scm (log10): defined to $log10.

	* scl.c: added $log10.

Thu Mar 20 21:09:19 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* Init.scm (scm:load): test for script files skips hopeless calls
	to link:link.
	(file-readable?): added.  Non-blocking reads first 2 characters of
	file.

Tue Mar 18 18:38:14 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* script.c (scm_cat_path scm_try_path scm_sep_init_try):
	(scm_find_impl_file dld_find_executable): moved from scm.c
	(script_find_executable script_P): added.
	(script_read_arg script_meta_arg_P): added.
	(script_process_argv script_count_argv): added.
	These functions implement `script meta-args' ala SCSH for unix
	and MS-DOS.

	* repl.c (scm_unexec): Now checks for execpath being set.
	(final_repl): No longer tries to set execpath.

	* dynl.c (init_dynl): Instead of trying to set execpath, now gives
	error message if NULL.

	* patchlvl.h (SCMVERSION): Bumped from 5a1 to 5b0.

Sat Mar 15 17:04:07 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* scm.c (main): Assumes called as a script when first argument
	(argv[1]) is "\\"; and finds execpath with
	dld_find_script_executable() instead of dld_find_executable().

	* findexec.c (dld_find_executable): Now prepends current working
	directory to any path with a `/' in it.
	(dld_find_script_executable): Added to resolve real executable
	pathname when program is invoked as a script.

	* Init.scm (read:sharp): #! now a balanced comment when first line
	ends with \ (backslash).  This is to support SCSH scripts.

	debugging with GDB 4.16.

Tue Feb 25 21:32:50 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* repl.c (iprin1): Now checks that a cell is actually in a heap
	before trying to print it.

	* rope.c (scm_cell_p): added.  Returns !0 if SCM argument is
	cell-aligned and points into a valid heap segment.

Sun Feb 23 21:21:21 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	* continue.h: SCM source now uses jump_buf, setjump, and longjump
	in lieu of jmp_buf, setjmp, and longjmp.  This should prevent name
	and declaration conflicts.

	* build.scm (include-spec): created to elide "-I" if scm-srcdir is
	"".

Sat Feb 22 20:45:58 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>

	Corrected long-standing
	(not (eqv? (integer->char 128)
		   (string-ref (make-string 1 (integer->char 128)) 0)))
	bug found by John Kozak <jk@noontide.demon.co.uk>.

Mon Dec  2 20:40:40 1996  Radey Shouman  <shouman@zianet.com>

	* eval.c (farlookup): Added, to handle memoized lookups in local
	environments with very wide or deep local environments.
	These print as (#@farloc-car iframe . idist).

Sat Nov  2 09:24:50 EST 1996 maximum entropy <entropy@zippy.bernstein.com>

	* ioext.c, scmfig.h: support for SGI (tested with SGI IRIX 5.2/gcc)

	* ioext.c (file_set_position): If a port is bidirectional
	(e.g. a socket) it may be necessary on some systems to perform a
	file positioning operation when switching between reading and
	writing.  This is required by ANSI C (ISO/IEC 9899:1990
	7.9.5.3).  Therefore, a	file-set-position on a bidirectional
	port should not signal an error if fseek generates an
	ESPIPE -- the fseek operation actually "succeeded" in that it
	reset the I/O direction flag for the FILE.

	* repl.c (input_waiting): R4RS requires that "char-ready?"
	return "#t" at end-of-file.  The semantics for "ioctl(...,
	FIONREAD, ...)" are such that it gives 0 on a socket that is
	closed (on the other side of the connection).  If the
	system has select(), use that instead to get the correct
	behavior.

	* socket.c (l_listen): Treat sockets that have been "listened"
	as input-ports.  This allows polling for new connections
	(e.g. with "char-ready?") instead of blocking in
	"socket:accept".

	* socket.c (l_accept): Fix type checking to agree with
	previous patch.

Wed Nov 13 17:11:59 1996  Aubrey Jaffer  <jaffer@localhost.bertronics.com>

	* sys.c (igc): fixed off-by-1 error for sizeof save_regs_gc_mark.
	(gc_mark): fixed off-by-1 error for sizeof(CONTINUATION).  These
	seem to fix a very obscure GC bug.

Tue Oct 29 10:47:41 1996  Aubrey Jaffer  <jaffer@localhost.bertronics.com>

	* Init.scm (exec-self): Added.

	* repl.c (init_repl): DUMP sets RESTART to EXEC-SELF.

Mon Oct 28 11:39:30 1996  Aubrey Jaffer  <jaffer@localhost.bertronics.com>

	etc. will work as the last expression in a loading file.
	(scm_execpath): Split out from scm_unexec.

Sun Oct 27 22:12:32 1996  Aubrey Jaffer  <jaffer@localhost.bertronics.com>

	(make-dll-archive linux): Now converts from ".o" objects to ELF
	".so" form and "links" the usual libraries.

	* Link.scm (usr:lib x:lib): dynamic linking fixed for (linux ELF)
	dlopen.  Libraries other than ".so" object not needed; eliminated
	by usr:lib and x:lib returning #f.

	* dynl.c (l_dyn_unlink): prints result of dlerror() on errors.

Thu Oct 10 14:05:14 1996  Aubrey Jaffer  <jaffer@martigny.bertronics>

	(uve_fill): Fixed error report.
	(lcount):
	(position): Made to work with 1-d shared bit-arrays.
	(aind): Added check for second argument, must be either
	an INUM, NULL, or a pair.  Without this, e.g.
                   (uniform-vector-set! <vector> 'x 0)
	starts cdr'ing down the symbol ...
	(array_inbp): Cleaned up to work with enclosed and huge arrays.

	* gsubr.c (gsubr_apply): Fixed error report.

	* scl.c (equal): Prevent fallthrough on last case, could cause
	wierdness if cases are added later.

	* ramap.c (ra_matchp): Fixed to allow any 1-d array of zero size
	to match a uniform vector, and to require all non-zero length
	dimensions of two arrays to match even after a zero length

	first array shape.
	(sc2array): Reshapes 0-d arrays as well as scalars.
	Added check to make sure 2nd argument is really an array,
	vector or uve.
	(ramapc): Changed to allocate fewer array headers when arguments
	are 1-d arrays.  (Still allocates more than strictly necessary.)
	(array_copy): Added check for scalar destination argument, since
	ra_matchp() will now promote scalars to arrays.

Sun May 12 00:52:51 1996  Aubrey Jaffer  <jaffer@jacal.bertronics>

	* build.scm (build): fixed HP-UX compile-dll-c-files.

Sat Apr  6 14:29:47 1996  Aubrey Jaffer  <jaffer@jacal.bertronics>

	* unexec.c (A_TEXT_OFFSET A_TEXT_SEEK ADJUST_EXEC_HEADER NO_REMAP
	TEXT_START HAVE_GETPAGESIZE SEGMENT_MASK): definitions moved from
	scmfig.h.

	* gmalloc.c (HAVE_GETPAGESIZE): copied definition here so that
	scm.h and scmfig.h won't be included for just one definition.

	* dump.c (scm_dump): reworked to use execpath as default second
	argument.  Removed "#include DUMP_CODE" abomination; using
	suppress parameters in build.scm

	* build.scm (build C-libraries): added dump (unexec) and nostart
	libraries to support dump.
	(build compile-commands): Added support for dump
	(build features): dump

	* scm.c (execpath): now a global which init_dump() also sets.

	after scm_ldfile(initpath) so command-line arguments can be
	processed after "Init.scm" is loaded.

	* build.scm (build platform): added record for MS-DOS so defaults
	don't cause errors when -p not specified.

Mon Jan  9 15:43:36 1995  Patrick LECOANET <lecoanet%sid1@cenaath.cena.dgac.fr>

	        arg is a subr.  Added cclo case.

	* unif.c (dims2ura): Fixed, it wasn't properly filling its result
	        sometimes.  Added range check for size of conventional arrays.
	(aind): Added range check when called as subr3.
	(array_inbp): Returns #t if called with a scalar and no
                index args -- APLish boundary case.
	(cvref): Now recycles enclosed array refs.
	(aset): Uses num2dbl for setting inexact array elts, so
	e.g. (array-set! <inexact-array> 0 ...) works.
	(array_contents): For strict option, wasn't returning an array
	whenever the base was non-zero, now less restrictive.
	(ra2contig): moved to ramap.c, as it calls ramapc().  To allow
	dynamic linking of ramap.c.
	(rafill): moved from ramap.c, to allow filling of arrays on
	creation without needing ramap.c.
	(uve_fill): Added, for filling uves / 1-d arrays without needing
	ramap.c.
	(uve_read, uve_write): (Re)added
	(ura_read, ura_write): Moved to ramap.c, now call uve_[read write].
	(ra2l): uses cvref instead of aref, maybe faster and works for
	enclosed arrays.
	(init_unif): Added feature 'string-case, to prevent require
	from nuking STRING-UPCASE!, STRING-DOWNCASE!
	(encl_array): Added range check for dimension args.

	* rope.c (num2dbl): Added, analogous to num2dbl.

	* scmfig.h Eliminated redundant #ifdef

	* scl.c (makdbl) Rearranged so that it tests for out of range
	double argument before assigning to float variable, this
	avoids causing SIGFPE on my Linux box.
	(equal): Fixed so that it doesn't need extern array_equal,
	allowing ramap.c to be dynamically linkable.

	* scm.c  Added documented variable *scm-version*

Thu Mar 21 00:14:29 1996  Aubrey Jaffer  <jaffer@jacal.bertronics>

	"require.scm" trampoline configuration method explained.

	* Init.scm (load:pre load:post): added to share code between
	scm:load and scm:load-source.  "require" is now loaded using the
	regular calls; trying to maintain SCM initializing without SLIB is
	too hard.

	* build.bat: Added for MS-DOS.

Fri Mar  1 23:47:57 1996  Aubrey Jaffer  <jaffer@jacal.bertronics>

	* scm.c (SYSTNAME): not redefined with DJGPP (both MSDOS and
	unix).

Sun Feb 18 09:29:57 1996  Aubrey Jaffer  <jaffer@jacal.bertronics>

	* subr.c (divbigint): fixed sign bug for 0 return value.

Sun Feb 18 00:29:43 1996  Per Bothner <bothner@cygnus.com>

	* gsubr.c (gsubr_apply): elided gratuitous make_vector call.

Sat Feb 17 11:50:41 1996  Aubrey Jaffer  <jaffer@jacal.bertronics>

	* Init.scm (*features*): string-case added.
	(string-upcase string-downcase string-capitalize): added.

	* unif.c (strcap): string-capitalize!

	* sys.c (sysintern): Now looks for (and uses) symbol already
	created.  This will eliminate order of linking and loading
	dependencies.

Tue Sep 26 20:37:25 1995  Aubrey Jaffer  (jaffer@jacal)

	* scm.texi (Evaluation): Enlarged description to include type
	folding.

Fri Sep 22 22:31:13 1995  Aubrey Jaffer  (jaffer@jacal)

	* scm.c scmfig.h (WINDOWS_NT): support added.  But what flag does
	Windows NT #define?

Sun Sep 10 13:37:44 1995  Aubrey Jaffer  (jaffer@jacal)

	* repl.c (scm_stack_trace): Added Scheme call "stack-trace" to
	print stack from exception handlers.
	(everr): Now processes all exceptions before longjmping to
	rootcont #ifdef CAUTIOUS.

	* Init.scm (user-interrupt): If stack-trace available, prints
	stack-trace and enters breakpoint.
	(break): Autoloaded.

Mon Aug  7 12:52:15 1995  Aubrey Jaffer  (jaffer@jacal)

	* scm.h (stacktrace): now a sys_protect.

	* subr.c (ilength): differentiated negative return codes;
	non-terminating returns -1, not a list -2.

Sat Aug  5 18:50:11 1995  Aubrey Jaffer  (jaffer@jacal)

	* repl.c (scm_print_stack): added.  Called by def_err_response.

	* eval.c (ceval): SCM stacktrace variable maintained and saved
	in CONT(cont)->other.stacktrace.  Under CAUTIOUS flag,
	checkargs1 label added to check special single argument calls.

Wed Jul 26 23:26:21 1995  Aubrey Jaffer  (jaffer@jacal)

	* repl.c (char_readyp): Now looks for BUF0 flag to determine if
	input_waiting() possible.

	* scm.c (init_scm run_scm main): BUF0 flag now set on cur_inp
	to indicate whether CHAR-READY? will work.

Wed Jul 19 13:25:01 1995  Shigenobu Kimura  <skimu@komachi.phys.s.u-tokyo.ac.jp>
	* dynl.c (l_dyn_main_call): Arguments to main (in DLD section)
	were reveresed!  Added hpux l_dyn_main_call.

Sat Jul  8 22:23:03 1995  Aubrey Jaffer  (jaffer@jacal)

	* Init.scm (scm:load): Internal define dependency problem fixed.
	Variable *interactive* set for invocation without options.

	* scm.texi: Guile WWW and citation added.

	* subr.c: logical (2's complement) operations rewritten to now
	work with bignums.  Logical procedure names changed to conform
	with Guile convention.

Fri Jun  9 13:47:58 1995  Aubrey Jaffer  (jaffer@jacal)

	* continue.c (stack_size):
	(make_root_continuation):
	(make_continuation):
	(free_continuation):
	(throw_to_continuation): moved from sys.c to make possible library
	module.

	* continue.h: created from setjump.h

	* scm.texi (Compiling And Linking): Documented l_dyn_main_call.
	(Type Conversions): added rope.c documentation.
	(Callbacks): split from "Calling Scheme From C".
	(Continuations): Rewritten to describe new "continue.c"

Fri May 19 01:32:12 1995  Aubrey Jaffer  (jaffer@jacal)

	* *.c: converted applicable uses of makfromstr with strlen to

	moved from scl.c and elsewhere.
	(makfromstrs makfrom0str makfromstr): moved from sys.c and posix.c
	(must_free_argv): new
	(scm_ldprog scm_ldfile scm_ldstr scm_evstr): moved from repl.c
	(makargvfrmstrs): chopped out of i_execv in ioext.c.
	makargvfrmstrs isn't really done correctly; it is GC leaky.
	It should return a SMOB which can be GCed, but this makes this
	C interface harder to use.

	* dynl.c (l_dyn_main_call): added procedure to call
	dynamically linked procedure with string arguments converted
	to argv and argc.  Written only for DLD.  Needs to be repeated
	for other dynamic linking regimes.

Tue Apr 25 10:24:42 1995  Aubrey Jaffer  (jaffer@jacal)

	* subr.c (make_string): Was silently failing for illegal 2nd args!

Sat Apr 15 23:18:47 1995  Aubrey Jaffer  (jaffer@jacal)

	* Link.scm (catalog:add-link): When feature is already in catalog,
	will only add new feature association to catalog if file exists.

Sun Apr  9 22:59:46 1995  Aubrey Jaffer  (jaffer@jacal)

	* repl.c (repl_driver): Now closes load port when ABORTing.

Sat Apr  8 21:35:43 1995  Aubrey Jaffer  (jaffer@jacal)

	From: Tom Lord <lord@cygnus.com>
	* scm.texi:
	Tcl Facilities::  Mutual calling between Tcl and Scheme.
	Tk Facilities::   Accessing Tk from Scheme.
	Gwish::           A Wish-like application of Guile.
	System Calls::    Psst.  Wanna write a manual section?
	Gscsh::           Shell and systems programming features.

	From: chen@adi.com (Franklin Chen)
	* scm.c (l_raise): uses raise() ifdef STDC_HEADERS, otherwise
	kill().

	From: Radey Shouman <shouman@ccwf.cc.utexas.edu>
	* scl.c (istr2int): Fixed complaints of overflow on octal numbers
	>= 2^BITSPERDIGIT.  Patch should make this work for all radix 2 <=
	radix <= 16.
	(num2ulong): Makes it work for negative bignum argments, and
	adds an overflow check.

	* ramap.c unif.c: There are several places in ramap.c, and
	raprin1() in unif.c, where I had assumed that an ivect or uvect
	elt would be representable no larger than an INUM.  This patch
	should fix these, also adding overflow checking for array
	arithmetic on uvects and ivects.

	Also, fixes aref, which assumed that if its argument was a smob
	that it was an array.  Changes cvref to return a real number when
	the imaginary part of an elt is 0.

Sat Mar 25 20:37:48 1995  Aubrey Jaffer  (jaffer@jacal)

	From: Don Bennett <dpb@netcom.com>
	* rgx.c: rewritten and extended.  The compile function now takes a
	string of optional flags.  New operations specific to the GNU
	regex library is conditionalized with _GNU_SOURCE.

	From: Radey Shouman <shouman@ccwf.cc.utexas.edu>
	* Iedline.scm (make-edited-line-port):
	* edline.c (lreadline): Added Gnu `readline' input editing
	(get ftp.sys.toronto.edu:/pub/rc/editline.shar).

	* unif.c (ra2contig): Fix a nasty bug ra2contig() (used for
	UNIFORM-ARRAY-WRITE / READ!) that produced arrays with undersized
	contents vectors.

	* eval.c (apply): Fix so that (APPLY <cclo> '()) works properly.

	* gsubr.c (make_gsubr): Give the arg number ASSERTion the right
	sense.
	(gsubr_apply): Add an ASSERTion to check for too many arguments.
	(gsubr_apply): Take the address of the temporary vector, so as to
	prevent its being optimized away and allowing gc of the vector.
	(This happened with Cray cc in the MAP and FOR-EACH code; I'm no
	longer able to find out if it would happen there.)

	* scm.texi: documentation finished for "posix.c" and "unix.c".

	* posix.c (scm_getgroups): added.

	* posix.c (makfrom0str): According to glibc.info, some field in
	structures like pwent may have NULL pointers.  Changed makfrom0str
	to return BOOL_F in this case.

Thu Mar  2 12:52:25 1995  Aubrey Jaffer  (jaffer@jacal)

	* time.c: CLKTCK set from CLOCKS_PER_SEC, if available.  Metaware
	HighC ported.

	* scm.h: USE_ANSI_PROTOTYPES now controls prototypes (was
	__STDC__).  This allows an overly fussy compiler to still have
	__STDC__.

	From: dorai@ses.com (Dorai Sitaram)
	* ioext.c (l_utime): include files fixed for __EMX__

Sun Feb 26 21:03:04 1995  Aubrey Jaffer  (jaffer@jacal)

	* sys.c (gc_mark gc_sweep): tc7_ssymbol now gets GCed because it
	gets used for non-GCed strings in scm_evalstr scm_loadstr.
	(mkstrport cwos cwis): changed so caller's name is passed into
	mkstrport().

	* repl.c
	(scm_eval_string scm_evalstr scm_load_string scm_loadstr): added
	for easier C to scheme callbacks.
	(loadport): variable added so lreadr() and flush_ws()
	increment linum only when reading from the correct port.
	(def_err_response): now handles ARGn for argument numbers > 5 and
	unknown position arguments.

	* dynl.c: Dynamic Linking now sets and restores *load-pathname*

	(add_feature): moved from repl.c.
	(features): init table removed (caused multiple symbols).

Fri Feb 24 23:48:03 1995  Aubrey Jaffer  (jaffer@jacal)

	* subr.c (append): Added check for bad arguments and fixed errobj.

Sun Feb 19 01:31:59 1995  Aubrey Jaffer  (jaffer@jacal)

	* ioext.c (exec execp): changed so that 2nd arguments is argv[0]
	(like posix) and renamed to execl and execlp.
	(execv execvp): added.

Sat Feb 11 17:30:14 1995  Aubrey Jaffer  (jaffer@jacal)

	* ioext.c (lexec): moved from repl.c and scm.c.
	(lexecp i_exec l_putenv): added.

	* unif.c (aset array2list array_ref cvref): uniform integers and
	unsigned integer arrays now handle full size integers (and
	inexacts) using num2long, num2ulong, long2num, and ulong2num when
	INUMS_ONLY is not defined.

	* scmfig.h (INUMS_ONLY): defined when INUMs are the only numbers.

Sun Jan 29 23:22:40 1995  Aubrey Jaffer  (jaffer@jacal)

Wed Jan 11 14:45:17 1995  Aubrey Jaffer  (jaffer@jacal)

	* scl.c (num2ulong): checks for bignum sign and magnitude added.

	* subr.c (logand logior logxor lognot): lognot restriction to
	INUMs removed.  Logand, logior, and logxor now will work for up to
	32 bit signed numbers.

Tue Jan 10 13:19:52 1995  Aubrey Jaffer  (jaffer@jacal)

	* repl.c (def_err_response): Circuitous call to quit() replaced
	with exit(EXIT_FAILURE);
	(everr): Now calls def_err_response() in interrupt frame if
	errjmp_bad or there are dynwinds to do.  This prevents silent
	failure in batch mode.

Mon Jan  9 00:12:14 1995  Aubrey Jaffer  (jaffer@jacal)

	* scm.texi (Trouble Shooting): Section converted from README.

	* Init.scm (-d filename): option added which does:
	(begin (require 'database-utilities) (open-database filename))

	* repl.c (handle_it): Now discards possibly used top freelist cell
	for GC safety.  Also now just punts if errjmp_bad.

	* scm.texi: converted from MANUAL.  GUILE documentation merged in.

Tue Jan  3 15:09:36 1995  Aubrey Jaffer  (jaffer@jacal)

	* makefile.os2: makefile for use with OS/2 toolkit nmake.

Sun Jan  1 21:17:36 1995  Aubrey Jaffer  (jaffer@jacal)

	* dynl.c Link.scm: names unified.  Libraries for HP-UX fixed.
	HP-UX dll suffix now ".sl".

	From: Shigenobu Kimura <skimu@komachi.phys.s.u-tokyo.ac.jp> *
	dynl.c (fcall): Fixed dynamic linking on hp9000s700 (or 720) HP-UX
	9.01 or 9.03.

Wed Dec  7 21:19:26 1994  Aubrey Jaffer  (jaffer@jacal)

	* ioext.c (l_open_input_pipe, l_open_output_pipe): moved from
	"Init.scm".

Mon Dec  5 16:55:21 1994  Aubrey Jaffer  (jaffer@jacal)

	* sys.c (i_setbuf0): added.
	(open_file): `0' in mode string now controls the buffered-ness of
	returned port.

	* Init.scm (slib:load-compiled): no longer silently fails if other
	than the first argument does not link correctly.

	From: Robert Sanders <rsanders@hrothgar.mindspring.com>

Sun Dec  4 21:47:08 1994  Aubrey Jaffer  (jaffer@jacal)

	* sys.c (free_storage): lord@cygnus.com pointed out that candle
	was being burnt from both ends.  Loop fixed.  Mallocs either
	leaking or counted wrong.

Sat Dec  3 22:32:59 1994  Aubrey Jaffer  (jaffer@jacal)

	* code.doc: added description of compiled closures.

Thu Nov 24 23:10:31 1994  Aubrey Jaffer  (jaffer@jacal)

	* socket.c MANUAL: most Scheme names for socket functions changed
	for consistency.
	* socket.c (socket:shutdown): added.  I can't imagine what use
	shutdown provides.  SOCKETs can be closed like any other port.
	Should socket:shutdown SOCKETs be closed?  Does having shutdown
	sockets cause file descriptors to be reused?  Socket:shutdown will
	be removed if no use is found for it.
	(tc16_sknm): added to encapsulate information retrieved from
	getpeername and getsockname.
	(socket-name:family socket-name:port-number socket-name:address):
	added to retrieve information from tc16_sknm.
	(inet:string->address inet:address->string inet:network
	inet:local-network-address inet:make-address): added.
	(gethost sethostent getnet getnetent getproto setprotoent getserv
	setservent): inquiry procedures added.

	* sys.c (makfromstrs(argc, argv)): added.  converts C array of
	strings to SCM list of strings.  If argc < 0, a null terminated
	array is assumed.

Sat Nov 19 00:20:58 1994  Aubrey Jaffer  (jaffer@jacal)

	* eval.c (l_proc_doc): added procedure-documentation.

	reopen-file open-pipe opendir readdir rewinddir closedir chdir
	umask rename-file isatty? access chmod mkdir rmdir stat utime
	raise): moved from "repl.c" and "sys.c".

Fri Oct 21 21:19:13 1994  Radey Shouman  <shouman@ccwf.cc.utexas.edu>

	* unif.c (ra2contig): now has a second parameter to indicate
	whether copying is necessary or not.  Eliminates gratuitous copy
	by UNIFORM-ARRAY-READ! when called with a noncontiguous array.

	(array_map): more liberal check on when ARRAY-MAP! can use
	array-ified asubrs.

Thu Oct 20 18:00:35 1994  Aubrey Jaffer  (jaffer@jacal)

	* sys.c (opendir readdir rewinddir closedir reopen-file): added
	under IO_EXTENSIONS.

Fri Oct 14 09:45:32 1994  Aubrey Jaffer  (jaffer@jacal)

	* posix.c (chown link pipe waitpid, kill, getpw, getgr, get*id,
	set*id): added.

	* time.c (l_raise l_getpid): added
	* subr.c (ulong2big):
	* scl.c (ulong2num): useful routines for system call data
	conversion moved from "time.c".

Thu Sep 22 14:48:16 1994  Aubrey Jaffer  (jaffer@jacal)

	* subr.c (big2inum): (more accruately) renamed from big2long.

Mon Aug 29 11:36:46 1994  Radey Shouman  <rshouman@hpcf.cc.utexas.edu>

	* unif.c: This is a large patch, but also a bit larger than it
	appears -- I moved a few function definitions around to eliminate
	gratuitous forward references.

	* unif.c repl.c (raprin1): Combined print routine for arrays with
	that for uves.

	* unif.c (UNIFORM-VECTOR-READ! and -WRITE): work with general
	arrays, by copying when necessary, renamed them to
	UNIFORM-ARRAY-READ! and -WRITE.

	* unif.c (ARRAY-CONTENTS): Generalized so that it returns a 1-d
	array even when the stride in the last dimension is greater than
	one, gave it an optional second argument STRICT, which makes it
	behave as it did before, returning an array/vector only if the
	contents are contiguous in memory.

	* unif.c (ARRAY-CONTIGUOUS?) Eliminated. Instead, use
		(lambda (ra) (array? (array-contents ra #t)))

	* unif.c code.doc (ramapc): unrolls arrays mapping into one loop
	if possible, to make this quick, changed the format of the array
	CAR, now uses one bit to indicate that an array is contiguous --
	this still allows a ridiculous number of dimensions.

	* scm.h (DSUBRF): dsubrs are mapped directly, to allow this I
	moved the typedef for dsubr and #define for DSUBRF to scm.h

	* unif.c (ARRAY-MAP!) taught something about subrs, now most subrs
	may be mapped without going through apply(), saving time and
	reducing consing.  +, -, *, /, =, <, <=, >, and >= are mapped
	directly as special cases -- for uniform arrays this is nearly as
	fast as the equivalent C, and doesnt' cons.  I've made sure that
	+, -, *, and / vectorize on the CRAY, this may be wasted effort
	but the effort is not great.

	* unif.c (ARRAY-COPY!) now copies many arrays of differing types
	to each other without going through the aref/aset, e.g. float ->
	double, double -> complex, integer -> float ...  This should make
	array type coercions for arithmetic faster.

	* unif.c (TRANSPOSE-ARRAY) Added, which returns a shared array
	that is the transpose of its first argument.  I think this does
	what an APL:TRANSPOSE would.

	* unif.c (ENCLOSE-ARRAY) Added, this returns an array that looks
	like an array of shared arrays, the difference being that the
	shared arrays are not actually allocated until referenced.
	Internally, the contents of an enclosed array is another array.
	The main reason for this is to allow a reasonably efficient
	implementation of APL:COMPRESS, EXPAND, and INDEXING.  In order to
	actually make an array of shared arrays, just use ARRAY-COPY!.

	* unif.c (cvref): Created internal version of aref(), cvref() that
	doesn't do error checking; Thus speeding things up.  Profiling of
	SCM running array code revealed that aref() was taking a
	surprising fraction of the CPU time

	TO DO:

	The mechanism for looking up the vectorized functions is a little
	kludgy, I was tempted to steal some of the CAR of the subr type to
	encode an offset into a table of vectorized functions, but this
	would make it more likely that dynamically loaded subrs lose thier
	names.

	It is almost possible to write APL:+ and friends now, it is just
	necessary to figure out the appropriate type of the returned array
	and allocate it, and to promote scalar arguments to arrays (with
	increments 0).

	This doesn't include vectorized REAL-PART, IMAG-PART,
	MAKE-RECTANGULAR ...

	I think some C support for APL:REDUCE and maybe INNER-PRODUCT will
	be needed for a reasonably fast APL.scm

	unif.c is getting quite big, time to split it up?

Sun Nov  7 10:58:53 1993    "Greg Wilson" <Greg.Wilson@cs.anu.edu.au>

	* scm.c config.h (TICKS ticks tick-interrupt): if TICKS is
	#defined, ticks and tick-interrupt work like alarm and
	alarm-interrupt, but with units of evaluation rather than units of
	time.

Mon Nov  1 18:47:04 1993    (jaffer at jacal)

	* MANUAL (chdir): documented.

	From: T. Kurt Bond, Adminisoft, Inc. <tkb@MTNET2.WVNET.EDU>:

	* repl.c sys.c (errno): VMS GNU C uses a special hack in <errno.h>
	to get the link-time attributes for the errno variable to match
	those the VMS C run-time library expects (it makes errno a
	preprocessor define so that the variable that the compiler sees
	has a special form that the assember then interprets), so if it is
	VMS and __GNUC__ is defined <errno.h> needs included.

	* setjump.h (SETJUMP LONGJUMP): SETJUMP and LONGJUMP changed to
	setjump and longjump. The VMS linker is case-indifferent.  VMS GNU
	C mangles variable names that have upper case letters in them to
	preserve their uniqueness.

	* sys.c (iprint iprin1): Now inline putc loops instead of calls to
	fwrite for VMS. The VMS `fwrite' has been enhanced to work with
	VMS's Record Management Sevice, RMS.  Part of this enhancement is
	to treat each call to `fwrite' as producing a seperate record.
	This works fine if you are writing to a stream_LF file or an
	actual terminal screen, but if you are writing to a file that has
	implied carriage control (such as a batch log file, or a mailbox
	used for subprocess communication), which is a more common file
	organization for RMS, each call to `fwrite' has a newline appended
	to it.  This causes much of the output to be incorrectly split
	across lines.

	* vmsgcc.com: created.

	* subr.c (lgcd): changed to work with borland C.

	* eval.c (eval): added checks to LAMBDA and LET.

	* eval.c (apply): now checks for null arg1 in lsubr.

Fri Apr 12 00:09:03 1991  Aubrey Jaffer  (jaffer at kleph)

	* config.h scm.h (SCMPTR): created to correct address arithmetic
	on stack bounds under Borland C++.  Borland C++ now runs scm2c.

	* sys.c (open_io_file, cw_io_file, file_position, file_set_pos,
	read_to_str) created (IO_EXTENSIONS)

	* config.h (IO_EXTENSIONS): defined

	* sys.c scm.c: lprin1f changed to iprin1

Wed Apr 10 12:58:59 1991  Aubrey Jaffer  (jaffer at Ivan)

	* sys.c (intern): line 850: for(i = alen;0 <= --i;)changed to
				    for(i = alen;0 < --i;).
	This fixed b_pos and v_pos mapping to the same symbol.

Wed Apr  4 00:00:00 1991  Aubrey Jaffer  (jaffer at kleph.ai.mit.edu)

	* released scm2b

Wed Apr  3 22:51:39 1991  Aubrey Jaffer  (jaffer at Ivan)

	* all files: eliminated types tc7_subr_2n and tc7_subr_2xn.
	Replaced with tc7_subr_2o and tc7_subr_1o so that all subr calls
	can be checked for number of arguments.

Tue Apr  2 23:11:15 1991  Aubrey Jaffer  (jaffer at Ivan)

	* code.doc: cleaned up.

Mon Apr  1 14:27:22 1991  Aubrey Jaffer  (jaffer at Ivan)

	* eval.c (ceval): fixed nasty tail recursion bug at carloop:.

	* scm.c (everr): still fixing error reporting.

	* eval.c subr.c: added flag PURE_FUNCTIONAL which removes side
	effect special forms and functions.

	* subr.c (substring): now allows first index to be equal to length
	of string

	* sys.c (lprin1f): dispatches on TYP16 of smobs.

	* scm.h: fixed typo in unused function defs.

Mon Mar 28 00:00:00 1991  Aubrey Jaffer  (jaffer at zohar.ai.mit.edu)

	* scm2a released: too many changes to record.  See code.doc.

Mon Feb 18 21:48:24 1991  Aubrey Jaffer  (jaffer at foxkid)

	* scm.h: types reformatted (TYP6 -> TYP7).

	* eval.c (ceval): Now dispatch directly on ISYMs in ceval.

Fri Feb 15 23:39:48 1991  Aubrey Jaffer  (jaffer at foxkid)

	* sys.c: #include <malloc.h> not done for VMS

Wed Feb 13 17:49:33 1991  Aubrey Jaffer  (jaffer at foxkid)

	* scm.c scl.c: added unsigned declarations to some char *
	definitions in order to fix characters having negative codes.

	* scm.h (MAKISYM, MAKFLAG, ICHR, MAKICHR, MAKINUM): Now cast to
	long so that their calls don't have to.  Changing MAKICHR fixed
	problem in scl.c (string2list) on IBMPC.

	* subr.c (quotient): support for `/' reintroduced; required by
	r3.99rs but not IEEE.

	* subr.c (char functions): added isascii tests for
	char-alphabetic, char-numeric?, char-whitespace?,
	char-upper-case?, and char-lower-case?.  Added test against
	char_code_limit to int2char.

	* subr.c (s_char_alphap): is subr_1 not lsubr.

	* test.scm: added tests for char-alphabetic, char-numeric?,
	char-whitespace?, char-upper-case?, and char-lower-case?.

	* sys.c: most `return;'s eliminated to reduce warning messages.
	Substituted breaks and reordered switch and if clauses.

Sun Feb  3 23:12:34 1991  Aubrey Jaffer  (jaffer at foxkid)

	* scm1-2: released.

	* sys.c (read-char peek-char) added code for EOF.

	* test.scm (leaf-eq?) added and file "cont.scm" removed.  I/O
	tests added.

	* sys.c (I/O functions) now check for input and output ports
	rather than just ports.

	* sys.c (lprin1f): occurences of stdout changed to f.  Newlines
	after printing port removed.

Thu Jan 31 22:52:39 1991  Aubrey Jaffer  (jaffer at foxkid)

	* subr.c (quotient): support for `/' removed; not required.

	* scm.c (wta): message for OUTOFRANGE fixed.

Mon Jan 28 12:45:55 1991  Aubrey Jaffer  (jaffer at foxkid)

	* eval.c (apply): added checks for number of arguments.

	* scm.h (CHECK_SIGINT): checks for blocked SIGINT.

	* sys.c (lprin1): added blocking and testing for SIGINT so that
	output won't hang on VMS.

	* scm.c (repl): added fflush call.

	* scm.c (err_head, wta): added fflush calls to error routines so
	that error message come out in proper order.
