+// This test checks the proper function of `-l link-arg=NAME`, which, unlike

+// options will be respected. In this test, compilation fails (because none of the

+// link arguments in the exact order they were passed in. `attribute.rs` is a variant
+// of the test where the flags are defined in the rust file itself.
