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.
