+* M_PI is no longer defined in SDL_stdinc.h, now the symbols SDL_PI_D (double) and SDL_PI_F (float) are available
 * SDL_GetWindowWMInfo() returns a standard int result code instead of SDL_bool, and takes SDL_SYSWM_CURRENT_VERSION as a new third parameter
 * SDL_RWFromFP has been removed from the API
