-This message announces the availability of Scheme release scm4e6.
-
-New in scm4e6 are:
-
-	* bench.scm (benchmark): added.  computes and display statistics
-	on "pi.scm" benchmark.
-	* Makefile (benchlit bench): targets added.  Append stats to file
-	"BenchLog".
-	* 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.
-	* 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.
-	* 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.
-	* Init.scm (exec-self): Added.
-	* repl.c (init_repl): DUMP sets RESTART to EXEC-SELF.
-	* repl.c (tryload): Made tail-recursive so that dump, quit, exit,
- 	etc. will work as the last expression in a loading file.
-	(scm_execpath): Split out from scm_unexec.
-	* unexec.c: All Updated from emacs-19.34 -- no changes necessary.
-	* gmalloc.c: 
-	* pre-crt0.c:
-	* ecrt0.c:
-	* unexelf.c: fixes Linux (ELF) dump bug.
-	* build.scm (platform): linux renamed linux-aout.  linux-elf fixed
- 	and renamed linux.
-	(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.
-	* eval.c (nconc2last): If CAUTIOUS is defined, checks that
-	APPLY's arglist and last element of arglist are LIST?s.
-	* sys.c (igc): symhash GC can now be disabled with
-	#define NO_SYM_GC.
-	* Init.scm (boot-tail): Added FSF --help and --version options.
-	Added --no-init-file as a synonym for -no-init-file.
-	* scm.texi (File-System Habitat): improved wording and added
-	examples.
-	* scm.texi (Top): Renamed sections.
-	* sys.c (mark_syms mark_sym_values): Split up mark_symhash() to
-	immunize against accidental pointers.
-	* repl.c (gc_ports_collected): added to instrument symbol GC.
-	* scm.texi (Debugging Scheme Code): Added section.
-	* eval.c (definedp): Changed from a memoizing macro to a `syntax'.
-
- From 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.
-
- From Radey Shouman  <shouman@zianet.com>
-
-	* eval.c (unmemocar): The code in unmemocar to deal with ILOCs was
-        never being executed.
-	* sys.c (intern): fixed (new) symhash GC bug.
-	* sys.c (igc): Added calls to mark_symhash() and sweep_symhash().
-	These GC unused symbols with a top-level value of UNDEFINED.
-	(mark_symhash): added.
-	(sweep_symhash): added.
-
- From Eric Hanchrow  <erich@MICROSOFT.com>
-
-	* scm.c (l_sleep): Ported to Windows NT (_WIN32)
-	* ioext.c: Ported to Windows NT (_WIN32)

+This message announces the availability of Scheme release scm5b3.
+
+New in scm5b3 are:
+
+	* 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.
+	* patchlvl.h (SCMVERSION): Bumped from 5b2 to 5b3.
+	* mkimpcat.scm: modified for new SLIB catalog arrangement.
+	* 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.
+	* Init.scm (home-vicinity): added.  Used to find "ScmInit.scm".
+	* unexsunos4.c: added from emacs.
+	* unexhp9k800.c: added from emacs.  Broken -- doesn't change the
+	segment sizes.
+	* unexalpha.c: added from emacs.
+	* build.scm (build C-libraries): changed horrible `supress-files'
+	field to `lib-support'.
+	(rebuild-catalog): added.  Called by dll and dlls methods.
+	* scm.texi (Compiling and Linking Custom Files): Added to describe
+	how to use "build.scm" with custom files.
+	* 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.
+	* 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.
+	* scm.h (const): defined to comment for hpux native cc.
+
+Fri Oct 10 00:18:40 1997  Peter E. Davis  <pete@media.mit.edu>
+
+	* unexhp9k800.c: added HP-UX unexec support.
+
+Sun Sep 28 14:48:10 1997  Radey Shouman  <shouman@zianet.com>
+
+	* ramap.c (array_imap): Fixed for zero-rank arrays arguments.
