+// ^ compiletest by default builds all aux files as dylibs, but we don't want that for proc-macro
+// crates. If we don't set this, compiletest will override the `crate_type` attribute below and
+// compile this as dylib. Removing this then causes the test to fail because a `dylib` crate can't
+// contain a proc-macro.
