With the following program:

use std;

use socket;

fn main(_argv: [str]) {
    let r = socket::connect("localhost", 8778u16);
    assert result::is_success(r);
}

using git head and the latest version of rust-socket (and a brand new build of rust-socket), the following build error occurs:

Things like this tend to happen when there are multiple matches for a single crate. Possibly try RUST_LOG=rustc::metadata::creader and see if the crate it's picking is the one you expect.

I don't think this is a problem in crate resolution. @nikomatsakis suggests it could be related to monomorphising.

More robust comment parsing

fixes rust-lang#2170

I haven't ported the entire test suite yet. Once we've done that, I will remove the old parsing system (or in fact, turn them into errors so that accidental usage of old-style comments will be detected)
