Now that I think about it, I'm running into this because I'm including 
SDL_opengl.h, which includes SDL_config.h. But looking at the 
documentation, it looks like all opengl needs is the various flags 
defined in SDL_config, not any of the libc defines. I know it'd break 
backwards compatibility if we moved the libc stuff into another file, 
but could this be considered in, say, 1.3?
