Pascal,

In commit f8eeaaf4180334a8e5c3582fe62a5f8176a8c124, build.c has already
changed, and I don't believe it's very compatible with this change.

See
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=f8eeaaf4180334a8e5c3582fe62a5f8176a8c124

Also, we'll need to see comments from H. Peter Anvin on this patch.
CC'ing him.
