What about old one? I have already complained in the early discussion that
`make W=1 ...` is broken by this change. Enabling it without fixing
_existing_ warnings on W=1 is not suitable for somebody. Now, I have to
modify my configs to disable WERROR because of inability to built at all.

(Yes, I understand that I may drop W=1, but that's not the point. since I
 want to have clean builds of a new code on level 1 of warnings)
