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.
