Right, but making argp truly standalone (without support from gnulib)
would require more modifications.  Issues that would need to be
considered include: alloca, getopt, strchrnul, mempcpy, strndup,
strnlen, a sysexits.h header file (and possibly more).  The goal with
my argp patches so far has been to only do the minimal amount of
modifications in libc that would be required to get argp sources to
run with the help of gnulib.  I'm sorry that I haven't succeeded in
making that clear.  Do you prefer if argp/* in libc would work
standalone on any C89 platform?

Thanks,
