The case to watch out for is a user enabling AltiVec for one or two source
files in a project, the rest of which don't have it enabled.

It's common for code on Mac OS to have a small portion test for the presence
of AltiVec and then use it if available. I'd imagine that many other
projects on other OSes might want the same capability. (Consider SETI@Home.)
