Hi!
I sent this in October and got very little feedback.

There is a problem in ompi_config_pthreads.m4 and
ompi_check_pthread_pids.m4 at least on Ubuntu Dapper
with both gcc and pgi.

The attached patch against v1.1.2 fixes the problem.

What happens is that in OMPI_INTL_POSIX_THREADS_LIBS_CXX it was
incorrectly setting PTHREAD_LIBS to $pl which at the time isn't set yet
and forgetting to reset LIBS on failure.

In OMPI_INTL_POSIX_THREADS_LIBS_FC it was resetting LIBS too quickly
resulting in -lpthread missing when checking for
PTHREAD_MUTEX_ERRORCHECK_NP

In OMPI_THREADS_HAVE_DIFFERENT_PIDS it didn't add THREAD_CFLAGS to
CFLAGS resulting in the code failing to link.
The testcode in itself was also broken so that some compilers failed
even to compile it.
