gcc 3.2 posix thread support on HP-UX

It means GCC cannot correctly build code which uses pthreads.

Certain critical functions in the C/C++ standard library may not be
re-entrant.  For example, perhaps the malloc and free functions are not
thread-savvy -- that would be bad.

I recommend using GCC 4.0.2.

Note:  in GCC 3.4, the option is --enable-threads=posix (no longer
--enable-threads=pthreads).
