I can't build HEAD kernel

[Jasse Jansson]

It stops with this message:

/usr/src/sys/net/route.c: In function 'route_init':
/usr/src/sys/net/route.c:140: error 'cpu' undeclared (first
use in this function)
blah, blah, blah.
Today I had to install from the 1.2 CD, getting the source,
rebuild with the DragonFly_Preview tag.
That worked fine. I also had no problem building
world with the tag HEAD sources, but buildkernel
halts with the message above.
Is this something known?
Maybe I should get one of Simons snapshots
and reinstall everything.
