+ work with it.
+
+1999-10-10 Radey Shouman <Radey_Shouman@splashtech.com>

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

+
+ * xtest.scm: Test key-press event.
+
+ * xevent.h: Generated by "xgen.scm"
+
+ * xevent.scm: Generated by "xgen.scm"
+
+ * requires.scm: Sample "require.scm".
+
+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>

+
+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.

+ stack trace, rather than colons so emacs will not try to balance
+ 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.

+1999-07-07 Radey Shouman <Radey_Shouman@splashtech.com>
+
+ * unif.c (arrayp): Fixed problem with immediate arguments.
+

+ 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.

+
+1999-05-12 Radey Shouman <Radey_Shouman@splashtech.com>
+
+ * eval.c (lookupcar): Combined some error checking cases.

+ (scm_macroexpand1):
+ (scm_extended_env):
+ (scm_env_ref): Low level support for hygienic macro expansion.
+
+ * 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?

+ (EQV? X (STRING->NUMBER (NUMBER->STRING X))) holds for inexact X.
+
+ * 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>
+
+ * sys.c (scm_maksubr): Added, returns a subr not (yet) bound to an
+ interned symbol, abstracts the addition of the subr_table entry.
+ (make_subr): Now uses scm_maksubr.
+
+ * gsubr.c (make_gsubr): Now uses scm_maksubr (was buggily using
+ old subr name encoding.)
+
+ * eval.c (make_synt): Now uses scm_maksubr.
+
+ * scm.h: Added prototypes for make_gsubr, scm_maksubr.
+
+1999-03-26 Arne John Glenstrup <panic@diku.dk>
+
+ * scm.h (ptobfuns): added const to puts() and fwrite() prototypes.
+
+ * gmalloc.c: fixed compilation on hpux.
+
+1999-03-26 Radey Shouman <Radey_Shouman@splashtech.com>
+
+ * 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>
+
+ * Init5d0.scm (exec-self): Undo *script* meta-argument processing.
+
+1999-03-18 Radey Shouman <Radey_Shouman@splashtech.com>
+
+ * Init5d0.scm (read:sharp): Simplified somewhat; again accepts
+ '#2((a b c) (1 2 3)) as array read syntax, with warning.
+
+1999-03-17 Radey Shouman <Radey_Shouman@splashtech.com>
+
+ * unif.c (raprin1): New write syntax for uniform vectors and arrays.
+ (array2list): (list2ura): Fixed for zero-rank arrays.
+
+ * Init5d0.scm (read:sharp): New read syntax for uniform vectors
+ 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.
+ The prototype is the symbol 'short, the print representation is
+ not currently readable. (Both items subject to change.)
+
+1999-03-11 Aubrey Jaffer <jaffer@ai.mit.edu>
+
+ * x.c (x:close): Merged from x:close-display and x:destroy-window.
+ Flushes after closing window.
+
+ * x.c: Use OPN and other bits in type-word. Fixed GC of closed
+ windows and displays.
+
+1999-03-10 Aubrey Jaffer <jaffer@ai.mit.edu>

+ 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,

+ and restart(); dowinds() now done after longjump.
+ (repl_driver): cur_inp being closed now indicates that SCM should
+ exit -- after printing error messages.
+ (def_err_response): err_pos = 0 after printing message. If
+ 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.

+ linked struct windframe on C-stack.
+
+1998-12-01 Radey Shouman <Radey_Shouman@splashtech.com>

+ 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,
+ setjump *must* be called with this argument before using a
+ safeport.
+
+ * repl.c (scm_stack_trace): (def_err_response): Use new

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

+ printed.

+ 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
+ little easier to read.
+
+ * sys.c (reset_safeport): Added, resets count and optionally
+ parent port on a safe-port.

+ (def_err_response): (handle_it): (repl_driver): (everr):
+ Now checks and dies horribly but predictably if def_err_response
+ is recursively entered.
+
+1998-11-20 Radey Shouman <Radey_Shouman@splashtech.com>

+
+ * sys.c (makesafeport): (safewrite): (safeputs): (safeputc):
+ (safeflush): Added support for `safe' ports for error messages,

+ respective alarms, so that restarting does not cause an error when
+ an alarm is pending.

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