It's a bug as the 4th argument being size_t predates FreeBSD. In FreeBSD base
-Werror is default but ports discourage it due to churn. In NSS -Werror was
enabled since 3.21 but only for Clang or GCC >= 4.8. For now, the plan is to
keep -Werror to avoid more facepalm situations.

Anyway, fixed in r481895. Thanks for reporting.
