downloademacs-1564080f0b24551765d7068b9fc02f6e5a78fea3.tar.gz
Clean up extern decls a bit.
* configure.ac (WERROR_CFLAGS): Don't disable -Wnested-externs. While we're at it, don't disable -Wlogical-op either. * src/bytecode.c: Include blockinput.h and keyboard.h rather than rolling their APIs by hand. * src/emacs.c: Include regex.h and rely on its and lisp.h's API rather than rolling them by hand. * src/lastfile.c: Include lisp.h, to check this file's API. * src/lisp.h (lisp_eval_depth, my_edata, my_endbss, my_endbss_static): New decls. * src/regex.h (re_max_failures): New decl. * src/unexcw.c, src/unexmacosx.c, src/unexw32.c: Rely on lisp.h's API rather than rolling it by hand. * src/vm-limit.c (__after_morecore_hook, __morecore, real_morecore): Declare at top level, to pacify GCC -Wnested-externs.
