+Mon Nov 18 22:56:11 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com>
+
+ * patchlvl.h (SCMVERSION): 4e6 released.
+
+ * bench.scm (benchmark): added. computes and display statistics
+ on "pi.scm" benchmark.
+
+ * Makefile (benchlit bench): targets added. Append stats to file
+ "BenchLog".
+
+Sun Nov 17 22:21:28 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com>
+
+ * scm.texi (Socket): added examples of chat servers and clients.
+ (Internet Addresses and Socket Names): enlarged from "Internet
+ Addresses".
+
+ * socket.c (l_connect): BUF0 was missing from mode bits set in
+ returned port.
+
+Sat Nov 16 22:02:39 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com>
+
+ * build.scm (build-params): Added compiler-options and
+ linker-options; added --batch-dialect and --script-name as aliases
+ for -h and -w.
+
+ * scmfig.h (HAVE_SELECT): Now defined for linux.
+
+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.

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

+ (scm_execpath): Split out from scm_unexec.
+
+Sun Oct 27 22:12:32 1996 Aubrey Jaffer <jaffer@localhost.bertronics.com>

+ (C-libraries): X11R6 moved library files on RedHat Linux. Linux
+ graphics library now has entry (doesn't default).
+ (compile-dll-c-files linux):
+ (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>

+ APPLY's arglist and last element of arglist are LIST?s.
+
+Sun Oct 6 16:40:54 1996 Radey Shouman <shouman@zianet.com>
+
+ * eval.c (unmemocar): The code in unmemocar to deal with ILOCs was
+ never being executed.
+
+Fri Oct 4 13:57:35 1996 Aubrey Jaffer <jaffer@martigny.bertronics>

+
+ * unif.c (array_rank): Was returning 0 for bit-vectors.
+ (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

+
+ * 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
+ dimension. Now promotes 0-d arrays as well as scalars to match
+ 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.

+ saving continuations.
+
+ * dump.c: removed. Contents moved to repl.c.

+ flags for non- SHORT_INT platforms.
+
+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.
+
+ * repl.c (repl_driver): added scm_evstr("(boot-tail)") call
+ 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>
+
+ * dump.c (dump): created.

+ 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

+ 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>

+
+Wed Feb 28 23:39:55 1996 Aubrey Jaffer <jaffer@jacal.bertronics>
+
+ * build.scm (build:build): library field `supress-files' added.
+ Used for supressing "findexec.c" when DLD is present.
+
+Sun Feb 25 00:29:47 1996 Aubrey Jaffer <jaffer@jacal.bertronics>
+
+ * scm.c (scm_find_impl_file): Tries hard to find Init.scm in
+ implementation vicinity.
+ (scm_try_path scm_cat_path): used by scm_find_impl_file.
+ (main): Changed to use scm_find_impl_file() and free pathnames
+ before exit.
+
+Wed Feb 21 23:27:43 1996 Aubrey Jaffer <jaffer@jacal.bertronics>
+
+ * findexec.c (dld_find_executable): extracted from DLD for

+ (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.

+
+ 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.)
+

+
+ * posix.c (scm_getgroups): added.
+
+ * posix.c (makfrom0str): According to glibc.info, some field in

+ 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.
+

+
+Fri Feb 24 23:48:03 1995 Aubrey Jaffer (jaffer@jacal)
+
+ * scm.c (scm_init_extensions COMPILED_INITS): Added so that

+ INUMS_ONLY is not defined.
+
+ * scmfig.h (INUMS_ONLY): defined when INUMs are the only numbers.

+ 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.

+
+ * 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):

+
+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

+
+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?
+
+
+Mon Sep 5 22:44:50 1994 Aubrey Jaffer (jaffer@jacal)

+
+Mon Aug 1 11:16:56 1994 Aubrey Jaffer (jaffer@jacal)
+
+ * time.c (curtime): replaces get-universal-time. Other time

+
+Thu May 12 00:01:20 1994 Aubrey Jaffer (jaffer@jacal)
+
+ * Link.scm: Autoload for hobbit now does (provide 'hobbit). This
+ allows hobbit to know if it is self compiling (although reloads of
+ hobbit will not be quite right).
+ ((compile file . args)): removed.
+
+ * makefile.unix (proto.h): removed.
+
+ * Transcen.scm: compile-allnumbers HOBBIT declaration added.

+ * unif.c: no longer uses pointer comparisons in loops. Should
+ fix problems on 8086 processors.
+ * unif.c (make_sh_array): Fixes MAKE-SHARED-ARRAY so that shared
+ arrays with only 1 element in some direction may still be
+ ARRAY-CONTIGUOUS?
+ (uve_write uve_read): Fixes bug in UNIFORM-ARRAY-WRITE,
+ UNIFORM-ARRAY_READ!. Now they do the right thing for shared
+ bit-arrays not starting at the beginning of their contents vector.
+ (array_contents ARRAY-SIMPLE?): ARRAY-CONTENTS may now return a
+ shared, contiguous, 1-d array, instead of a vector, if the array
+ cannot access all of the contents vector. ARRAY-SIMPLE? removed.
+ (array-fill!): a replacement and generalization of
+ UNIFORM-VECTOR-FILL!.
+ (raequal): Combines with uve_equal(), providing also ARRAY-EQUAL?
+ ARRAY-EQUAL? is equivalent to EQUAL? if all its arguments are
+ uniform vectors or if all are arrays. It differs from EQUAL? in
+ that a shared, 1-d array may be ARRAY-EQUAL? to a uniform vector.
+ for example
+ (define sh (make-shared-array '#(0 1 2 3) list '(0 1))) ==> #1(0 1)
+ (equal? '#(0 1) sh) ==> #F
+ (array-equal? '#(0 1) sh) ==> #T

+
+ * 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.

+
+ * 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.

+
+ * 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.

+
+ * 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.

+
+ * 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.
