Both of these files are part of gnulib.  As a matter of policy, we do
not change those files in our repository.  Instead we update from
gnulib's repository from time to time.

Can you please send this problem report and patch to
<bug-gnulib <at> gnu.org> ?

I'm closing this bug, since there's nothing for us to do in Guile.  If
you find any clang-related problems in Guile itself, please let us know.

     Thanks,
       Mark
