snprintf is required by POSIX going back to SUSv2, so it's pretty darn
hard to imagine any currently-used platform that hasn't got it.  Even
my now-extinct dinosaur gaur had it (per digging in backup files).
I think we could certainly assume its presence in the branches that
require C99.  Even before that, is anybody really still building on
nineties-vintage platforms?

Yeah, that might be a better answer than playing whack-a-mole with
these sorts of warnings.
