/* These headers are from sdl12-compat, and are intended to give just enough
functionality to let you build an SDL-1.2-based project without having the
real SDL-1.2 available to you. */

/* This is all kinda dicey. Just pretend we have most of these no matter what.
   Hopefully most apps don't actually rely on this. :/  These defines would
   need to be correct (and usually generated by a configure script) if these
   headers were to be used to build the real SDL 1.2, but they are only
   intended for building apps against sdl12-compat. */
