Making changes sdl2_input.c to build on Fedora 19 (x86_64). I assume that these changes reflect changes to SDL2 made prior to the "final" release of SDL2 (https://github.com/DeedleFake/sdl/issues/2). SDL version installed with yum: SDL2.x86_64 = 2.0.0-3.fc19; SDL2-devel.x86_64 = 2.0.0-3.fc19; SDL2.i686 = 2.0.0-3.fc19. Code is completely untested as I don't have RTCW pak files to hand.
