Improvements to the MinGW crossbuild. Should now build with default tools from Debian mingw packages, though you need Win32 version of libSDL with the necessary headers and so on in addition. 64-bit builds not tested and probably won't work. Tested on Debian 7.0, earlier won't work. binutils-mingw-w64-i686 gcc-mingw-w64-i686 mingw-w64-i686-dev
