This is exactly the point I was trying to make.  Most platforms
will not use the vectoring support.  It simply doesn't fit
accurately the model used by the media instructions used on
cpus.  Altivec is the perfect match, and this isn't surprising
since the vector support in GCC was created to support Altivec.
