If this change had contained a test, it would have caught it.

Alternatively, we'd need to catch compiler warnings on the build farm,
but if the installation is too old to recognize %zu, who knows what else
it'll warn (or not warn) about.  Eventually, users of such systems tend
point these things out, but that could take a while.
