I was able to get some HP-UX related fixes into 2.2, but there are
still some open problems on HP-UX (somewhere on SourceForge), for
which I lacked the time for further investigation. I'm not currently
using Python, but I'd nevertheless offer to cooperate with anybody
interested in better support for HP-UX (10.20 and 11)--I'm just not
motivated enough to do it alone.

aCC is the C++ compiler; the unbundled ANSI C compiler is cc. But
since the OP was able to compile Python, I doubt he used the bundled
compiler--you wouldn't get that far with a K&R compiler, I think.

My guess is that, like this problem, most problems on HP-UX are in
configure. 10.20 and threads is, ahem, a bit problematic; the DCE
threads are _not_ POSIX threads.
