Yeah, that's what I thought,  I just compiled it on recently as
someone suggested that to try.  I believe it can be toggled on and off
in the frontend anyways.  I'll get rid of it for future compilations.

Yeah, I've been reading that thred you posted too.  Even with the flag
in there it's not enabled, but I left it in incase it xvmc-openGL does
become stable, it will be compiled in automatically.  (I store my
configure arguments in a script so that I can update svn easily
without having to remember to enable everything.
