pub extern functions aren't considered unsafe from other crates

[doy]

// crate.rs
#[crate_type = "lib"];

pub extern "C" {
    fn rand() -> libc::c_int;
}

// test.rs
extern mod crate;

fn main () {
    println(fmt!("%?", crate::rand()));
}

Compiling these as separate crates doesn't produce an error, but compiling them both as part of the same crate does, as does compiling a crate which uses a function from a different crate which was explicitly marked as unsafe. It seems like this should be consistent.

Still relevant. and I think this should require unsafe block.
