>Description:
I am trying to update 8.1-RELEASE-p2 to 8.1-RELEASE-p4 but make buildkernel fails:
/usr/src/sys/dev/vge/if_vge.c: In function 'vge_attach':
/usr/src/sys/dev/vge/if_vge.c:1025: error: 'mcic' undeclared (first use in this function)
/usr/src/sys/dev/vge/if_vge.c:1025: error: (Each undeclared identifier is reported only once
/usr/src/sys/dev/vge/if_vge.c:1025: error: for each function it appears in.)
*** Error code 1

Stop in /usr/obj/usr/src/sys/GENERIC.
*** Error code 1
>How-To-Repeat:
1) create file: /usr/local/etc/supfile with content:
*default host=cvsup7.ru.FreeBSD.org
*default base=/usr
*default prefix=/usr
*default release=cvs
*default tag=RELENG_8_1
*default delete use-rel-suffix
src-all
2) csup /usr/local/etc/supfile
3) cd /usr/src
4) make buildworld
5) make buildkernel
>Fix:
I don't know any workaround.
