I just did a 'man gcc' on our PostgreSQL FreeBSD server and read:
      -pthread             Link a user-threaded process against libc_r instead of libc. Ob-             jects linked
intouser-threaded  processes  should  be  compiled             with -D_THREAD_SAFE.
 

so it seems it is a link flag, and they have a compile flag no one told
me about.  I already have it configured as a compile flag.  Let me fix
that.  I am working on the thread test program so I will commit it all
at once.
