make buildkernel fails what now ?

[Brent Bailey]

Im updating a backup server running FBSD 4.9, of ours by doing the whole
make buildworld make buildkernel procedure..This machine was originally a
4.8 server that i did a succesful make buildworld upon the last release..

anywho i updated src with cvsup and then did the following

cp -Rp /etc/ /etc.old
/usr/sbin/mergemaster -p

cd /usr/obj
chflags -R noschg *
rm -rf *

COMPILED SRC
cd /usr/src
make buildworld
make buildkernel KERNCONF=MYKERNEL

upon the last command it compiles away for about 20 minutes
the ends in error

/usr/src/sys/modules/ipfilter../../contrib/ipfilter/netinet/ip_fil.c:1325:
value not ignored as it ought to be
Error Code 1

Stop in  /usr/src/sys/modules/ipfilter

Where do i go from here ??
Do i re-cvsup   and then try to redo make buildkernel ??  IF i reboot will
the kernel be trying to run from mismatched src ?

any help is greatly appreciated
