A set of kernel headers intended to be usable for userspace and glibc
compilation is being maintained by Mariusz Mazur <mmazur@kernel.pl>: see
<http://ep09.pld-linux.org/~mmazur/linux-libc-headers/>. The headers
shipped with the kernel aren't meant to be included by userspace
programs.

This incompatibility is already fixed in these headers.

In general, if you have libc/kernel-header userspace problems, the
place to fix them is in the linux-libc-headers: don't hack up glibc
or the kernel headers proper for such things.

What we need these days is a stable, fast, anti-aliased root beer
