buildkernel fails

Hi,

I did a buildworld+buildkernel on my workstation today and buildkernel fails with:

cc -c -O2 -frename-registers -pipe -fno-strict-aliasing  -std=c99 -g -Wall
-Wredundant-decls -Wnested-externs -Wstrict-prototypes  -Wmissing-prototypes

My src tree is at the latest rev. No /usr/obj. I'm currently running
CURRENT from May, 5th.

Any ideas?
