There are only three animals showing this warning (ayu, batfish,
demoiselle) so it likely requires particular clang versions
as well as the right -W switches.
Maybe a cast would silence it, but your draft seems
underparenthesized. (Which raises the question of whether we
should be using a macro for this at all --- probably there's
not much risk of double-evaluation being a problem, but a
static inline would remove the risk.)
