Thanks.  They are in sync now.  There are some standalone portability
problems which are being sorted out, and I will be submitting patches
for them.  The intention is that the patches should work both within
libc and for standalone applications via gnulib.  Once this is done,
the argp files should IMHO be added to the script in gnulib that
update the files from libc, and the canonical place for the files is
libc.

Btw, do you know what happened to linewrap.* in libc?  ChangeLog
mention them several times (1996-1997), and argp detect and use
linewrap if available, but the files seem to have disappeared from
libc long time ago, without any traces in ChangeLog.  If that was
intentional, I think it would help readability to remove all the
linewrap cruft in argp, although I won't send patches for this until
gnulib argp has stabilized for a while, since it doesn't cause real
problems.
