+                               Optimized
+
+               20040822        Reimplementation. Improvements:
+                               - initial_value != 1 works properly
+                               - wait can be aborted via CTRL-C
+                               - doesn't nest per task
+
+               20040513        SDL_SemTryWait() function return value fixed
+
+               20040510        ObtainSemaphore inserted in SDL_SemWaitTimeout
+
+               20040504        Debug lines added
