Description of problem:
After using up2date to upgrade kernel and sources to kernel-2.6.9-22.0.1.EL I 
can no longer build a custom kernel. I followed the steps at http://www.redhat.
com/docs/manuals/enterprise/RHEL-4-Manual/release-notes/as-x86/ to get the 
sources. I now get the following error:

[root@d400 linux]# make bzImage
  CHK     include/linux/version.h
make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.
  CHK     include/linux/compile.h
