[xemacs-hg @ 2002-07-23 08:34:59 by youngs]
2002-07-15 Jerry James <james@xemacs.org>
* make-docfile.c: Change whitespace and organization to reduce the
size of the diff against FSF Emacs sources and synch to Emacs 21.2.
Remove unused DO_REALLOC.
Mark XEmacs changes and additions more clearly.
Reintroduce previously deleted Emacs code inside #if 0 ... #endif.
* make-docfile.c (next_extra_elc): Replace goto with do-while.
* make-docfile.c (main): Put XEmacs-only args in one place.
* make-docfile.c (write_c_args): Change buff to buf to match
Emacs. Replace pointer arithmetic with simpler array syntax.
* make-docfile.c (scan_c_file): Note that DEFSIMPLE and DEFPRED no
longer exist. Correct the "name too long" test (off by one).
Die with message if a DEFUN has no docstring instead of hanging.
* make-docfile.c (scan_lisp_file): Introduce while loops used in
Emacs sources to skip consecutive blank lines.
2002-07-21 John Paul Wallington <jpw@xemacs.org>
* process.el (substitute-env-vars): New function; sync with
GNU Emacs 21.1.50.
(setenv): Add optional arg SUBSTITUTE-ENV-VARS; sync with
GNU Emacs 21.1.50.
2002-07-20 Mike Sperber <mike@xemacs.org>
* eval.c (run_post_gc_hook): Use more correct flags when running
post-gc-hook.
2002-07-20 Mike Sperber <mike@xemacs.org>
* process-unix.c (child_setup): Don't try to close file
descriptors for chid process once again---it's already being done
in close_process_descs.
(unix_create_process): Call begin_dont_check_for_quit to inhibit
unwanted interaction (and thus breaking of X event synchronicity)
in the child.
2002-07-15 Jerry James <james@xemacs.org>
* lisp.h: Make Qdll_error visible globally.
* symbols.c (check_sane_subr): Revert 2002-06-26 change.
Check only if !initialized.
* symbols.c (check_module_subr): Add parameter. Duplicate
check_sane_subr checks, but signal an error instead of asserting.
* symbols.c (defsubr): Use check_module_subr parameter.
* symbols.c (defsubr_macro): Ditto.
