[MPlayer-dev-eng] [PATCH] OS/X, Darwin _altivec

[Steven M. Schultz]

Hi -

	I ran into a couple bugs in the ./configure script when building
	MPlayer on OS/X tonight.   There was a single '=' instead of '=='
	in a test, but the more serious bug was the unconditional setting
	of _altivec to 'no'.   It appears that _altivec was being reset to
	'no' while testing for altivec.h - Darwin has altivec instructions
	but not altivec.h

	Patch appended below for your consideration.

	Steven Schultz
