I am assuming that -Wall does not include -Wformat and that we do not enable -Wformat on the Mac, iOS, or Windows bots as I have not seen this failure. We should look to enable -Wformat on these bots.

No, -Wall does include -Wformat (at least in GCC).

I don't know about that. Certainly the Apple builds seem to be less-strict about such issues.
