Iain Sandoe turned up one more bug for me in regression testing. Another 
case where I mis-categorized a built-in, this time as "VSX" versus 
"AltiVec".  As with the other two, I'd appreciate consideration of this 
patch along with the rest of the patch set. Thank you!

(Iain tells me that this is all there is to find, so that should be the 
end of the "spare" patches for now.)

Much obliged,
Bill
