+
+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.
+

+	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>

+
+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

+	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.
+
+Fri Mar 7 21:12:17 EST 1997  Aubrey Jaffer  <jaffer@scm.bertronics.com>

+	
+	* eval.c (renamed_ident): Renamed RENAME-IDENTIFIER to 
+	RENAMED-IDENTIFIER.
+
+	* eval.c (m_case): Avoid renaming data at the head of each
+	clause.
+
+Wed Feb 26 10:17:59 1997  Aubrey Jaffer  <jaffer@martigny.ai.mit.edu>
+
+	* Macro.scm (macro:compile-syntax-rules):
+	* Init.scm (copy-tree): use of copy-tree changed to @copy-tree.
+
+	* eval.c (copy-tree): renamed to @copy-tree.
+
+	* sys.c (igc): test added for calls to igc within igc.
+
+	* unif.c (raprin1): calls ipruk() instead of using cells if
+	called during gc.
+
+	* scl.c (bigprint floprint): no longer try to allocate cells if
+	called during gc.
+
+	* .gdbinit (runscm verbose errobj scm load eval): added for
+	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>
+
+	* repl.c (lreadr): uncommented line 640 to allow reading balanced
+	comments at end of files.

+	than implementation-vicinity.
+
+	* Init.scm (warn): added.
+
