unresolved import using separate files, but not mod statements

[durka]

This code compiles:

//! lib.rs

mod A {
    pub mod B {
        use super::*;

        pub struct S;
    }

    pub mod C {
        use super::*;
        use super::B::S;

        pub struct T;
    }

    pub use self::C::T;
}

use A::*;

$ rustc --crate-type lib lib.rs -Awarnings
$

However, splitting the code into files causes compilation to fail:

//! lib.rs

mod A;

use A::*;

//! A/mod.rs

pub mod B;
pub mod C;

pub use self::C::T;

//! A/B.rs

use super::*;
pub struct S;

//! A/C.rs

use super::*;

use super::B::S;

pub struct T { i: i32 }

$ rustc --crate-type lib lib.rs -Awarnings
lib.rs:3:5: 3:10 error: unresolved import
lib.rs:3 use A::*;

I am not sure whether use C::T or use self::C::T is correct; regardless, replacing the latter with the former in A/mod.rs produces a similar error:

$ rustc --crate-type lib lib.rs -Awarnings
A/mod.rs:4:9: 4:10 error: unresolved import `C::T`. Maybe a missing `extern crate C`?
A/mod.rs:4 pub use C::T;
                   ^

This appears to work now.
