Fixed bug #853 Ludwig Nussel 2009-10-18 05:34:18 PDT src/joystick/linux/SDL_sysjoystick.c has some problems: - test_bit() might break with strict aliasing - test_bit() assumes array is Uint32 but its actually "unsigned long" on 64bit systems sizeof(long) != sizeof(Uint32). - the keybit array is too small - the arrays are unitialized so the number of detected buttons is quite random
