So I entirely ignore W=1 issues, because I think so many of the extra
warnings are bogus.

But if this one in particular is causing more problems than most -
some teams do seem to use W=1 as part of their test builds - it's fine
to send me a patch that just moves bad warnings to W=2.

And if anybody uses W=2 for their test builds, that's THEIR problem..
