Not a problem.  I've pushed the patch with the updated attribution, with
this ChangeLog entry:

2010-02-10  Eric Blake  <address@hidden>

        Avoid uninitialized use of $U.
        * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Ensure $U is
        set if automake did not define it.
        * THANKS: Update.
        Reported by Heiko Schlichting, via Julien Élie.

Don't work too hard, make some time for fun as well!
