Jean,
Thanks for the excellent advice. The changing of
/usr/include/{asm,linux} did work for me! For RedHat 9 people though,
those two directories are provided by the RPM glibc-kernheaders, upon
which gcc depends. So there was no clean & simple way to install/remove
packages to remove the two dirs. I temporarily moved them, symlinked my
kernel build in, and compiled things. Worked the first time.
As an aside, I suppose it's bad form by either glibc-kernheaders or
gcc 3.2.2 to get anyone into this situation. Does anyone know if gcc
3.2.3 behaves better or it was the lack of RedHat packages writing to
/usr/include/{asm,linux} that enabled Christian's solution to work?
