    Issue #7272:  Add configure test to detect whether sem_open works
    properly, and use this to skip test_multiprocessing on platforms
    where sem_open raises a signal.  This should fix some FreeBSD buildbot
    failures for test_multiprocessing.
  ........
    r76558 | mark.dickinson | 2009-11-28 10:44:20 +0000 (Sat, 28 Nov 2009) | 4 lines

    Issue #7272, continued:  don't re-use existing HAVE_BROKEN_POSIX_SEMAPHORES
    to indicate that semaphores aren't available;  define a new variable
    POSIX_SEMAPHORES_NOT_ENABLED instead.
