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.

/* Compare version strings:
|
|
|
|
This function compares strings S1 and S2:
|
|
1) By PREFIX in the same way as strcmp.
|
|
2) Then by VERSION (most similarly to version compare of Debian's dpkg).
|
|
Leading zeros in version numbers are ignored.
|
|
3) If both (PREFIX and VERSION) are equal, strcmp function is used for
|
|
comparison. So this function can return 0 if (and only if) strings S1
|
|
and S2 are identical.
|
|
|
|
It returns number >0 for S1 > S2, 0 for S1 == S2 and number <0 for S1 < S2.
|
|
|
|
This function compares strings, in a way that if VER1 and VER2 are version
|
|
numbers and PREFIX and SUFFIX (SUFFIX defined as (\.[A-Za-z~][A-Za-z0-9~]*)*)
|
|
are strings then VER1 < VER2 implies filevercmp (PREFIX VER1 SUFFIX,
|
|
PREFIX VER2 SUFFIX) < 0.
|
|
|
|
This function is intended to be a replacement for strverscmp. */
