Thanx Johnathan to flip me back om my feet :)

I got the picture, I will be as despotic as gcc is :) I will setup a
uniq global setup in our Makefile -fno-builtin-exp2, it should not
really hurt because I don't think we have place where we really meant
we wanted the math.h version, and on the spot force #define exp2(x)
__builtin_exp2((x)) when one really want to do math.

Again thanx
Cheers,
Phi
