Fixed bug #935

Patrice Mandin

Hello,

I originally added pth support for threads in SDL 1.2 because on the Atari
platform we did not have any thread library.

I think pth support could be removed from SDL 1.3 for two reasons:

- Atari platform removed

- pth does not provides real (preemptive) threads, because it is user space,
and expect the application to call one of its function to give CPU to another
thread. So it is not exactly useful for applications, that expect threads to
run simultaneously.
