Looking at the Rust libc bindings I see the following:
https://github.com/rust-lang/libc/blob/72c40004a3568849055c0bab5c92c9975b4eb132/src/unix/bsd/freebsdlike/freebsd/freebsd11/mod.rs#L8
https://github.com/rust-lang/libc/blob/72c40004a3568849055c0bab5c92c9975b4eb132/src/unix/bsd/freebsdlike/freebsd/freebsd12/mod.rs#L5

Seems to have changed to 64 bit for FreeBSD 12 and up?
