Known false alarm; the patchew processing queue is backlogged, and is
testing patches against a version of qemu.git that does not yet have
patches for newer gcc compliance incorporated, while at the same time
having recently upgraded its testing environment to use the newer gcc
that warns.  Commit 97b583f4 will silence the noise, once patchew
catches up to using it.
