[xemacs-hg @ 2002-04-01 03:58:02 by ben] bug fixes (e.g. ballooning on X windows) Makefile.in.in: Try to make the Makefile notice if its source Makefile.in.in is changed, and regenerate and run itself. Use a bigger default SHEAP_ADJUSTMENT on Cygwin; otherwise you can't compile under Mule if a Lisp file has changed. (can't run temacs) TODO.ben-mule-21-5: update. mule/mule-cmds.el: Hash the result of mswindows-get-language-environment-from-locale, since it's very expensive (and causes huge ballooning of memory under X Windows, since it's called from x-get-resource). cl-extra.el, code-files.el, files.el, simple.el, subr.el, x-faces.el: Create new string-equal-ignore-case, based on built-in compare-strings -- compare strings ignoring case without the need to generate garbage by calling downcase. Use it in equalp and elsewhere. alloc.c, bytecode.c, chartab.c, data.c, elhash.c, emacs.c, eval.c, event-Xt.c, event-unixoid.c, extents.c, file-coding.c, fileio.c, fns.c, glyphs.c, gutter.c, lisp-union.h, lisp.h, mule-charset.c, nt.c, process-unix.c, process.c, specifier.c, symbols.c, sysdep.c, sysdep.h, text.c, toolbar.c: Try to implement GC triggering based on percentage of total memory usage. Not currently activated (percentage set to 0) because not quite working. Add `memory-usage' primitive to return XEmacs' idea of its memory usage. Add primitive compare-strings, compatible with FSF 21.1 -- can compare any part of two strings, optionally ignoring case. Improve qxe() functions in text.c for text comparison. Use RETURN_NOT_REACHED to try to avoid warnings about unreachable code. Add volatile_make_int() to fix warning in unix_send_process().
