From: Max Horn
Subject: SDL_HasAltiVec; BUGS file
the attached patch adds SDL_HasAltiVec to SDL CVS. Note that at this
point, this only works on MacOSX (and maybe darwin). I don't know how
to properly add a test for e.g. Linux/PPC at this point. I found an
email which might help in doing so:
http://zebra.fh-weingarten.de/~maxi/html/mplayer-dev-eng/2003-01msg00783.html
However, since I have no way to test on a non-OSX PowerPC system, I am
not comfortable blindly adding such code... I just hope that if
somebody from the Linux/PPC (or FreeBSD/PPC, or whatever) community
notices this, they'll jump up and provide a patch for us ;-)
