For anyone who cares: gcc compile oddity

I was watching a build of netbsd-7 scroll past (it cam be amusing
watching gcc printing warnings about code in gcc...) when I saw this
one fly past.

To me this looks like it might indicate a real error, rather than
just typical gcc noise.

If anyone cares, here is the warning (the build continued happily).
(All of this is from a netbsd-7 checkout that is, I believe, up to date.)
