Hey Puneet,

The threading support in mapthread.c is enabled only if -Dunix is
defined as well as -DUSE_THREAD.  For OS X, you'll need to edit
your mapfile to add this to THREADS.

Now that there is a Win32 pthreads library, I think it is about
time that we think about removing the the #ifdef unix entirely.

cheers,
Sean
