// Crates that are resolved normally have their path canonicalized and all symlinks resolved. This
// did not happen for paths specified using the `--extern` option to rustc, which could lead to
// rustc thinking that it encountered two different versions of a crate, when it's actually the same
// version found through different paths.
//
// This test checks that `--extern` and symlinks together can result in successful compilation.
//
// See <https://github.com/rust-lang/rust/pull/16505>.
