No, it's OK to modify lib/fnmatch*.  Any changes should be merged into
the GNU libc source once they stabilize.  I'll submit a glibc patch in
due course.  I've already made several changes to lib/fnmatch*, since
the current glibc versions don't work on non-glibc platforms (it's
been a while since they were ported).

We shouldn't patch config.hin, since it's generated automatically.

I will also patch m4/fnmatch.m4 as follows, but as it happens the
fnmatch.m4 patch isn't needed for diffutils 2.8.2, and it requires
autoconf+automake so I left it out in the patch that I emailed earlier
today.  (This part of the patch has already been merged into Autoconf
CVS, so that we can remove m4/fnmatch.m4 once Autoconf 2.54 comes out.)
