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, it it's the SDL.DLL which uses this API,
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!
