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 into user-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.
