I was trying to upgrade my 9.0-CURRENT amd64 after clang
was updated, but i got following error:

===> sys/boot/i386/cdboot (all)

My /etc/src.conf has:

.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=

Any hints?
