I don't think I see much of an analogy here. Anyway, there's FSF gcc
and there's Apple gcc, both can run on OSX. Do distinguish between them,
you need either different toolset name, or some extra feature.

The only practical difference I know, is that with different toolset name,
if you have a condition that applies to both gcc version, you'd have
to write:


Such conditions are mostly needed to workaround platform differences,
and I have no idea if having to write two lines instead of one is
big enough annoyance.
