Do scalar parameters to AltiVec builtins need to have exactly the

2nd argument to vec_dst can be any integral type. This is a gcc bug.
Oh Paolo....
Actually, I suspect that the culprit here is altivec.h -- it really 
shouldn't
feed the 'const int' (literal) parameters to 
__builtin_types_compatible_p;
the el cheapo overload resolution should occur on the vector arguments 
alone.
