// 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.
// See https://github.com/rust-lang/rust/pull/16505

// This test checks that --extern and symlinks together
// can result in successful compilation.
