We have a lot of options that are vaguely similiar to this.  It's also reminiscent of -iprefix.  But I actually 
think the closest analogy is to -B.  Its effect on header and library paths is the same as -B, but it 
doesn't change the search for compiler executables.

And while Syd is right that Apple would find this feature useful, I don't think there's anything about it 
that's specific to Apple or Darwin.  I expect it to be generally useful for people who are trying to deal 
with multiple similar-but-not-identical versions of an operating system.
