Ewe.  I bet we added that test program _after_ we got threads working on
Win32.  That program, and the flags detection configure checks have made
threads configuration almost fool-proof, so I don't think we should
change any of that.

As far as the Win32 API, I am unsure.  Let me see if I can hack up
thread_test.c to use libpq/pthread-win32.c to see if I can get that
working.
