My point was just that there's nothing that forces every compiler to
make "-I<dir>" the way to set the include path.  It happens to be that
way for a few popular ones like icc because people generally just do
what GCC does.  But nothing stops someone from making a compiler where
it uses lowercase i, for instance.  These options HAVE to be compiler
specific.

I'm trying to make that work, actually.  It's very hard.
