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 * unexhp9k800.c: added HP-UX unexec support. Sun Sep 28 14:48:10 1997 Radey Shouman * ramap.c (array_imap): Fixed for zero-rank arrays arguments. -=-=- Scm conforms to Revised^4 Report on the Algorithmic Language Scheme and the IEEE P1178 specification. Scm is written in C and runs under Amiga, Atari-ST, MacOS, MS-DOS, OS/2, NOS/VE, Unicos, VMS, Unix and similar systems. ASCII and EBCDIC are supported. Documentation is included explaining the many Scheme Language extensions in scm, the internal representations, and how to extend or include SCM in other programs.
