+// `raw-dylib` is a Windows-specific attribute which emits idata sections for the items in the
+// attached extern block,
+// so they may be linked against without linking against an import library.
+// To learn more, read https://github.com/rust-lang/rfcs/blob/master/text/2627-raw-dylib-kind.md
+// `#[link_ordinal(n)]` allows Rust to link against DLLs that export symbols by ordinal rather
+// than by name. As long as the ordinal matches, the name of the function in Rust is not
+// required to match the name of the corresponding function in the exporting DLL.
+// This test checks the correctness of this feature by comparing its output against expected
+// output.
