[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.
