(In addition to rnk's question: We build with -Werror, but Wliblto seems
unaffected by this. Because of that, our bots didn't catch the new warning
and we only noticed this when a human did a local build after we updated
compilers and saw a wall of warnings. It'd be good if Wliblto was affected
by -Werror too.)
