HP-UX 10.20 & g++ 2.95.2: Have to use -threads

Part of the problem is in configure.  Under hpux 10.20, if configure
finds pthread.h, it enables threads.  It is not possible to disable
threads with --enable-threads=no or --disable-threads.  I discussed
this with Jeff a few months ago.  I wanted to change configure so
that it disabled threads if pthread.h wasn't found.  As a side effect,
the --enable-threads option would work.

I wanted to be able to disable threads because there is an unresolved
conflict with --enable-shared.  The above problem is another reason
why forcing the use of threads when installed is wrong.
