I am getting a build fail with vdpau since

     autoconf: Enable missing-prototypes errors when available.

     After the removal of the dri driver link test, this should help avoid
     the original problem that it was designed to catch: The warning about
     a missing prototype due to typoing a function name scrolling by in the
     Mesa build spew, and you not noticing until you try to run an
     application and it falls back to swrast.
