* 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!
