annotate src/video/x11/SDL_x11dyn.c @ 4383:daf9e6037596 SDL-1.2

Gregory Smith Another one for the "How did this ever work?" file: when DX5_HandleMessage is called with WM_ACTIVATEAPP, it goes past the end of the 2-element SDL_DIdev array and if there doesn't happen to be a 0 in the memory next to it, crashes. Patch against SVN attached.
