[xemacs-hg @ 2003-02-15 10:15:54 by ben] autoload fixes, make-doc speed improvements Makefile.in.in: Run update-elc-2 with -no-autoloads to avoid multiple autoload-loading problem. configure.usage: Document quick-build better. make-docfile.el: Use `message' (defined in this file) in place of `princ'/`print', and put in a terpri, so that we get correct newline behavior. Rewrite if-progn -> when and a few similar stylistic niceties. And the big change: Allow MS Windows to specify the object files directly and frob them into C files here (formerly this was done in xemacs.mak, and very slooooooooooooooooooowly). Due to line-length limitations in CMD, we need to use a "response file" to hold the arguments, so when we see a response file argument (preceded by an @), read in the args (a bit of trickiness to do this), and process recursively. Also frob .obj -> .c as mentioned earlier and handle other junk dependencies that need to be removed (NEEDTODUMP, make-docfile.exe). update-elc-2.el: Use :test `equal' in call to set-difference. update-elc.el: Put back commented out kill-emacs, update header comment. xemacs.mak: Delete old unused code that checks SATISFIED. Move update-elc-2 up to be near update-elc. Run update-elc-2 with -no-autoloads to avoid multiple autoload-loading problem. Don't compute make-docfile args ourselves. Pass the raw objects to make-docfile.el, which does the computation (much faster than we could). Don't delete the DOC file, split the invocation into two calls to make-docfile.exe (one direct, one through make-docfile.el), etc. In general, all we do is call make-docfile. Add proper dependencies for DOC-file rebuilding so it doesn't get done when not necessary. Implement quick-building here: not building the DOC file unless it doesn't exist, as the quick-build docs say. Makefile.in.in: Don't delete the DOC file. Implement quick-building here: not building the DOC file unless it doesn't exist, as the quick-build docs say. config.h.in, emacs.c: Nothing but niggly spacing changes -- one space before a paren starting a function-call arglist, please.
