[Manfred Antar]

I get this error when trying to buildworld on current i386.
It's been this way for awhile Any Ideas ?

===> boot/i386/boot0 (all)
clang -O2 -pipe  -DVOLUME_SERIAL -DPXE -DFLAGS=0x8f  -DTICKS=0xb6  -DCOMSPEED="7 << 5 + 3" -ffreestanding -mpreferred-stack-boundary=2  -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -msoft-float -std=gnu99    -c /usr/src/sys/boot/i386/boot0/boot0.S
