I guess you could probably drop those typedefs for MSVC, because SDL
headers don't really need it.

typedef char            Sint8;
typedef unsigned char   Uint8;
typedef short           Sint16;
typedef unsigned short  Uint16;
typedef int             Sint32;
typedef unsigned int    Uint32;

I found above  are the common types used in SDL.  And modifying
sdl_config_win32.h shouldn't be a bad idea, it's a config file anyway.
