Often there is a FREE compiler available, and that might not
be 'ansi'.  That does not mean it is "the kernel compiler", as
if that is the only compiler which can compile the kernel...
People use the free compiler because it's FREE, not because
they have no other choice.

In any case, the point I was making was that if you use __P(),
and if you have some kind of autoconfigure setup, then the
decision to use __P() should NOT key off the platform.  It
should key off whether the compiler chosen by the user will
understand prototypes.
