Weird pthread portability issue.

[macd68]

This code works fine on linux (2.6 kernel GCC v 3.3.3):

                                 while (1) {
                                           pthread_cond_wait(&waited_on,&notify_mutex);
                                           printf("%d: Sent or received timequery from client thread %d at %d.\n",getpid(),seen,time(NULL));
                                           seen = 0;
                                 }

The anticipated behavior is blocking till pthread_cond_signal() from another thread obviously.

Under FreeBSD 6.0 (gcc 3.4.4) this same code (event loop) results in non-blocking behavior.

Any ideas?
