Recent gnulib changes required this change.  Attached is a patch for head,
but I also applied a similar patch to the branch.

2007-07-20  Eric Blake  <address@hidden>

        Fix 'make distcheck' issues.
        * bootstrap: Add more files that might be more up-to-date in
        gnulib.
        * Makefile.am (EXTRA_DIST): No longer distribute removed diff.
        * config/m4/gnulib-cache.m4: Update to latest gnulib.
