The attached seems enough to silence it for me.

Should we back-patch this? I suppose, but how far? It seems to fall
under the rules we established for back-patching into out-of-support
branches, ie it silences compiler warnings but shouldn't change any
behavior. But it feels like a bigger change than most of the other
things we've done that with.
