[xemacs-hg @ 2003-02-06 06:35:47 by ben] various bug fixes mule/cyril-util.el: Fix compile warning. loadup.el, make-docfile.el, update-elc-2.el, update-elc.el: Set stack-trace-on-error, load-always-display-messages so we get better debug results. update-elc-2.el: Fix typo in name of lisp/mule, leading to compile failure. simple.el: Omit M-S-home/end from motion keys. update-elc.el: Overhaul: -- allow list of "early-compile" files to be specified, not hardcoded -- fix autoload checking to include all .el files, not just dumped ones -- be smarter about regenerating autoloads, so we don't need to use loadup-el if not necessary -- use standard methods for loading/not loading auto-autoloads.el (maybe fixes "Already loaded" error?) -- rename misleading NOBYTECOMPILE flag file. window-xemacs.el: Fix bug in default param. window-xemacs.el: Fix compile warnings. lwlib-Xm.c: Fix compile warning. lispref/mule.texi: Lots of Mule rewriting. internals/internals.texi: Major fixup. Correct for new names of Bytebpos, Ichar, etc. and lots of Mule rewriting. config.inc.samp: Various fixups. Makefile.in.in: NOBYTECOMPILE -> BYTECOMPILE_CHANGE. esd.c: Warning fixes. fns.c: Eliminate bogus require-prints-loading-message; use already existent load-always-display-messages instead. Make sure `load' knows we are coming from `require'. lread.c: Turn on `load-warn-when-source-newer' by default. Change loading message to indicate when we are `require'ing. Eliminate purify_flag hacks to display more messages; instead, loadup and friends specify this explicitly with `load-always-display-messages'. Add spaces when batch to clearly indicate recursive loading. Fassoc() does not GC so no need to gcpro. gui-x.c, gui-x.h, menubar-x.c: Fix up crashes when selecting menubar items due to lack of GCPROing of callbacks in lwlib structures. eval.c, lisp.h, print.c: Don't canonicalize to selected-frame when noninteractive, or backtraces get all screwed up as some values are printed through the stream console and some aren't. Export canonicalize_printcharfun() and use in Fbacktrace().
