Fixed bug 3336 - Failure to build with MinGW-w64

Kai Sterker
There are already patches available from mingw64 that fix the issue

https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-SDL2

With those applied, I could compile SDL2 without problems. But of course, it would be preferable if SDL built cleanly from source.
