It has something related to compiler speicific header files. I 
think. For that you can't use std headers in kernel, then you add a 
flag -nostdinc, but then the compiler specific headers were gone, so 
you have to get them back, and -iwithprefix include magically done 
that. This is just my random guess. I've been hit by this for my own 
modules and I have to copy exactly the CFLAGS in kernel to my 
Makefile. So I guess. 8)
