+1999-11-09  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* sys.c (scm_env_v2lst): Made tolerant to argc of zero,

+	allocated on the C stack, rather than a uve.
+
+	(ramapc): (ramap): (ramap_cxr): (array_imap): (array_for_each): (rafe):

+
+1999-09-11  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>
+
+	* Xlibscm.texi (Event): Documented x:event-ref.
+
+1999-08-26  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* sys.c (scm_egc): More robust test for sufficient cells in
+	freelist.
+
+1999-08-24  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* eval.c (wrapenv): Will no longer wrap an already wrapped
+	environment.
+
+	* repl.c (def_err_response): Now prints "expand-time environment"
+	message only when relevant.

+	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.

+
+        * eval.c: (ceval_1): Made EVAL tail recursive.
+	Cleaned up some stack tracing cases, renamed POP_TRACE
+	to TOP_TRACE, since POP_TRACE sounds as though it should be the
+	inverse of PUSH_TRACE.
+
+	(ceval_1): Now modifies stack trace only after an estk
+	frame may be pushed, that is, when some invocation of eval may
+	modify the environment.  The bottom of the stack trace (the form

+	`scm_trace'.  Nested expressions involving primitives now give
+	more accurate stack traces, without a speed penalty.
+
+	(map): (for_each):  Always push an estk frame for the sake of stack
+	tracing.

+	parens.
+
+1999-07-20  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* build: Require build.scm in program-vicinity, since build.scm
+	may not be installed in implementation-vicinity.
+
+1999-07-19    <radey@cartman.colorage.net>
+
+	* repl.c (def_err_response): Changed setjump to setjmp when
+	setting up safeport.
+
+1999-07-11  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>
+
+	* Makefile (incdir): Added to abstract include directory location.

+
+	SINGLES no longer need to be #DEFINEd in order to allow fvects.
+

+
+1999-07-06  Radey Shouman  <Radey_Shouman@splashtech.com>

+	* r4rstest.scm: Added named LET test for scope of init forms.
+	* eval.c (m_let): Changed scope of init forms in named LET, to
+	conform to R5RS, in response to posting of Allegro Petrofsky
+	<Allegro@Petrofsky.Berkeley.CA.US> to comp.lang.scheme
+
+1999-07-04  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>
+
+	* 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".
+
+1999-05-31  Aubrey Jaffer  <jaffer@ai.mit.edu>
+
+	* Xlibscm.texi: Pulled out of "scm.texi".
+
+1999-05-29  Aubrey Jaffer  <jaffer@ai.mit.edu>
+
+	* scl.c (llog2 lpow10): renamed from log2 and lpow10, which
+	conflicted with djgpp include file /d/djgpp/include/math.h.
+
+1999-05-15  Dai INUKAI  <GAF05426@nifty.ne.jp>
+
+	* Transcen.scm (expt): R5RS: 0^z is 1 if z = 0 and 0 otherwise.

+
+        * Macroexpand.scm (macro:expand): Added for hygienic macro expansion.
+
+	* 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.
+
+1999-05-09  Aubrey Jaffer  <jaffer@ai.mit.edu>
+
+	* r4rstest.scm (test-eq?-eqv?-agreement): Added tests for eqv?

+
+	* scl.c (iflo2str): Revamped so that (EQV? X (STRING->NUMBER
+	(NUMBER->STRING X))) holds for floating point X.  Somewhat as in:
+	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.
+
+1999-04-15  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>
+
+	* Makefile (require.scm): Added constructor.
+
+1999-04-01  Radey Shouman  <Radey_Shouman@splashtech.com>

+
+	* gsubr.c (make_gsubr): Now uses scm_maksubr (was buggily using
+	old subr name encoding.)

+
+	* scm.h: Added prototypes for make_gsubr, scm_maksubr.

+	* Init5d0.scm (identity): Now a subr: CR.
+	* eval.c
+	* gsubr.c
+	* repl.c
+	* scm.h
+	* subr.c
+	* sys.c (SNAME): Pointers to subr names now kept in a mallocated
+	data structure, the top 16 bits of the CAR of a subr is an index
+	into this table.  Eventually this should help support eg generic
+	arithmetic.
+
+1999-03-25  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* sys.c (scm_grow_gra): Fixed error in mallocated accounting, made
+	increment grow with allocated size.
+
+1999-03-22  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>

+1999-03-17  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* unif.c (raprin1): New write syntax for uniform vectors and arrays.

+	and arrays.
+
+1999-03-16  Radey Shouman  <Radey_Shouman@splashtech.com>
+
+	* x.c (scm2int_pair): Generalized to accept uniform vectors and
+	arrays.
+
+	* eval.c
+	* ramap.c
+	* repl.c
+	* rope.c
+	* scl.c
+	* scm.h
+	* sys.c
+	* unif.c
+	Added uniform vector type for signed short integers, tc7_svect.

+	err_exp is not defined.
+
+	* repl.c

+
+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>

+
+1998-12-02  Aubrey Jaffer  <aubrey_jaffer@splashtech.com>

+	* sys.c safeport now includes jmp_buf, to which it will longjump
+	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

+
+	* scm.texi (Data Type Representations): PTOBs had wrong code and

+	printed.
+	(err_head): More robust test for output to stderr, to
+	decide whether to call perror or not.
+
+	* sys.c (init_types): Initialize sys_safep to tmp_errp.
+	(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

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

+	(safeflush): Added support for `safe' ports for error messages,

+
+	* Init5c4.scm (alarm-interrupt) (profile-alarm-interrupt)
+	(virtual-alarm-interrupt) Now initially defined to turn off their
+	respective alarms, so that restarting does not cause an error when
+	an alarm is pending.
+
+	* sys.c (gc_mark): Now marks the header of smobs and ptobs, so the
+	mark function doesn't have to.
+	* unif.c:
+	* record.c:
+	* rgx.c:
+	* rope.c:
+	* scm.h: Ptob and smob mark functions modified to not mark headers.
