Fixed bug #570
SDL_SemWaitTimeout in src/thread/generic/SDL_syssem.c line 179 (SVN trunk):
--sem->count;
should be
if (retval == 0) {
--sem->count;
}
Without this, sem->count will underflow on timeout effectively breaking the
semaphore. It appears that the implementation has been wrong since the initial
revision.
