Yep, this is another false positive from gcc.  I've mailed a proposed
workaround to Xin Li, but for now, if you compile world and kernel with
gcc, use NO_WERROR= and WERROR= in your make.conf.  Especially the
kernel still needs a bunch of fixes to make it work with gcc again.

It's a pity the gcc tinderboxes have been taken offline.  Maybe this can
be added to the FreeBSD Jenkins instance now?
