sdl-ios-xcode: src/video/xbios/SDL

annotate src/video/xbios/SDL_xbios.c @ 1336:3692456e7b0f

Use SDL_ prefixed versions of C library functions. FIXME: Change #include <stdlib.h> to #include "SDL_stdlib.h" Change #include <string.h> to #include "SDL_string.h" Make sure nothing else broke because of this...
