Fixed bug #171 SDL_config.h is no longer in CVS. Instead, configure will generate it for systems that use configure, and we always copy SDL_config.h.default to SDL_config.h before generating a snapshot or release archive. Also fixed a couple of uninstall issues.

/* Include the SDL main definition header */
#include "SDL_main.h"

#ifdef main
#undef main
int main(int argc, char *argv[])
{
	return(SDL_main(argc, argv));
}
#else
/* Nothing to do on this platform */;
#endif
