Make the following changes by hand, and run 'admin/merge-gnulib'. * .gitignore: Add lib/malloc/*.gl.h. * admin/merge-gnulib: Copy lib/af_alg.h and lib/save-cwd.h directly from Gnulib, without worrying about Gnulib modules, as these files are special cases. (AVOIDED_MODULES): Remove malloc-posix. * lib/malloc.c, lib/realloc.c, m4/malloc.m4, m4/realloc.m4: * m4/year2038.m4: New files, copied from Gnulib. * lib/malloca.c, lib/malloca.h: * m4/close-stream.m4, m4/glibc21.m4, m4/malloca.m4: Remove. These are either no longer present in Gnulib, or are no longer needed by modules that Emacs uses. * oldXMenu/AddPane.c, oldXmenu/Addsel.c: Include XmenuInt.h first; needed for new Gnulib. * src/xmenu.c: Call emacs_abort, not abort.
