Between 20111021 (r180287) and 20111128 (r180617), several 30_threads tests
started to FAIL on Tru64 UNIX:

This may be due to this change:

2011-10-22  Jonathan Wakely  <jwakely.gcc@gmail.com>

        PR libstdc++/50196
        * acinclude.m4 (GLIBCXX_HAS_GTHREADS): Don't depend on _POSIX_TIMEOUTS.
        * configure: Regenerate.
        * include/std/mutex (timed_mutex, recursive_timed_mutex): Define

On this platform, _POSIX_TIMEOUTS is missing in <unistd.h>.

I find that those tests are UNSUPPORTED on the 4.6 branch.
