Without actually delving into the SDL and Mplayer code, I think its
quite a messy issue. -mwindows expects the entry point at WinMain, while
-mconsole (or without -mwindows) expects it as main(), so its not a good
idea to filter out these. sdl-config and libSDL_main is supposed to
abstract these.

With both mingw and mingw-w64?

Escape with '\' or use single quotes. Or use mingw-w64, you shouldn't
need to use MS SDK.
