When I try to build kernel-source-2.5.69 with kernel-package, I get the
following message:

I understood that this was supposed to be changed from a warning to a
error sometime soon; I just didn't realize it was *so* soon. If you
need the .config or anything else, let me know.

Closing these reports. Please submit bugs against the various kernel
source packages, either to fix the bug or to select a compiler, which
still accepts this coding style.
