I think that's a sensible change -- but I think we're past the point
where we can make these kind of changes.

HP's compiler is in its final stabilization phase, and so is Intel's.

I don't think we should be doing anything but clarifying at this
point.

What we could do is add this as a note.  (Note that it would have been
better to do X, but we didn't.  Oops.)
