[MPlayer-users] [PATCH] _altivec setting lost on OS/X

[Steven M. Schultz]

Hi -

	Normally _altivec means that the G4/Altivec instructions are
	supported and on a OS/X system _altivec is "yes" UNTIL line ~1995
	in ./configure.   Then _altivec is set to "no" and is used to mean
	that "altivec.h" was (or was not) found.

	I wondered why _altivec was "no" on a G4 OS/X system ;)

	The patch below works by saving and restoring _altivec around the
	one test.   If there's a better way that's fine too but this I believe
	preserves the intent of _altivec

	Cheers,
	Steven Schultz
