+   We compile SDL into a DLL on OS/2. This means, that it's the DLL which
+   creates a new thread for the calling process with the SDL_CreateThread()
+   API. There is a problem with this, that only the RTL of the SDL.DLL will
+   be initialized for those threads, and not the RTL of the calling application!
+   To solve this, we make a little hack here.
+   We'll always use the caller's _beginthread() and _endthread() APIs to
+   start a new thread. This way, if it's the SDL.DLL which uses this API,
+   then the RTL of SDL.DLL will be used to create the new thread, and if it's
+   the application, then the RTL of the application will be used.
+   So, in short:
+   Always use the _beginthread() and _endthread() of the calling runtime library!
