#[link] not before extern is silently ignored

[kornelski]

#[link(name="bad")]
fn main() {
}

compiles without warnings. I would expect warning that the link is unused or in the wrong place.

This causes a gotcha: if you insert any code between link and extern you suddenly get linker errors, because there's no -llibrary flag added.

#[link(name="library")]

struct SURPRISE();

extern {
    pub fn library() -> ();
}

fn main() {
    unsafe {
        library();
    }
}

I've got bitten by this when I've moved #[link] next to extern crate and #![crate_id] statements that I thought it belongs with.

This should be fixed by RFC #2 whenever it gets implemented.

Yup!
