It may be a kludge, it may also be necessary at times.  What if you
really want/need to have a #include depend on a define?  In the KERNEL
case, -I is easy, since the non-kernel case is typically a standalone
utility which has a seperate makefile (or at *least* a seperate target)
Doing if/then/else in a makefile isn't as easy (assuming it's even
possible) as doing it in C.  Having a seperate target is a worse kludge
than the #ifdef you were trying to avoid in the first place.

Sounds like it's Reisser's cpp that is broken.  (Seems like I've heard
that before...)

We're getting a bit off the track gang, time for:
