# Okay, the people at RedHat have to break everything they can possibly even attempt to.
# So, we have to look in /usr/src/linux-2.4/include for header files given their brain dead
# crappy installation.  (Mind you, I'm a RedHat user myself, so I suppose I'm just as
# stupid as they are).  Everyone else who is mildly sane of course links /usr/include/linux
# to their working kernel source directory, the way God himself does, of course
# (assuming He's running Linux -- which we all know He must).
