I've tried to build kernels on an i386 and amd64 machine and I fail with this:

#   compile  SPEEDY-CURRENT5/tcp_input.o
/usr/src/../tools-current/bin/x86_64--netbsd-gcc -mcmodel=kernel
-mno-red-zone -ffreestanding -O2 -Werror -Wall -Wno-main

/usr/src/sys/netinet/tcp_input.c:1582: warning: implicit declaration
of function `callout_active'

*** Failed target:  tcp_input.o

This is the same failure with GENERIC as well.

Also anoncvs.netbsd.org is down... Kind of wondering what's going on.
