What gcc are you using? I am not getting any warning at least with gcc
"(SUSE Linux) 4.3.1 20080507 (prerelease) [gcc-4_3-branch revision
135036]"

$ make ipc/msg.o
CHK include/linux/version.h
CHK include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-x86
CALL scripts/checksyscalls.sh
CC ipc/msg.o
