Building Python 2.3 on HP-UX 10.20 - pthread failure

[Dan Cescato]

When I try to build Python 2.3 on HP-UX 10.20 using their cc compiler,
I get a compile failure.  It comes down to Python/thread_pthread.h
deciding that my machine is an unsupported system, as documented in
the README file.  ("Systems defining PY_PTHREAD_D4...").  Apparently,
Python 2.3 doesn't like their implementation of pthreads.  However, in
the "Platform specific notes" section, there is a note about HP-UX
10.20 which makes me believe that someone has gotten it to work.

The application we're writing in Python needs pthreads.  Is there an
upgrade patch available from HP that will get this to build?  Our
technology director has ruled out gcc.  Has anyone gotten this to
build?
