	New Revision: 28996

	Log:
	Fix libswscale compilation on non-x86, hopefully without breaking MinGW64 again.

This change was non optimal, correct would have been to revert the offending commits
if no time was available to find a clean fix.

Originally committed as revision 29003 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
