I've never observed this myself. If a new compiler warning is added to gcc and if it produces warnings that are not useful for kernel code usually Linus or someone else is quick to suppress that warning. Another argument in favor of W=1 is that the formatting of kernel-doc headers is checked only if W=1 is passed to make. Bart.
