- (dtucker) [auth-pam.c] Since people don't seem to be getting the message
that USE_POSIX_THREADS is unsupported, not recommended and generally a bad
idea, it is now known as UNSUPPORTED_POSIX_THREADS_HACK. Attempting to use
USE_POSIX_THREADS will now generate an error so we don't silently change
behaviour. ok djm@
