You can test that on any system, by passing `-target x86_64-windows-msvc` to the e.g. clang command in a lit test, so you can get test coverage for that aspect of the functionality regardless of what system you're running. Most tests in `clang/test/Driver` work that way.

Ah ok. So instead of having `! REQUIRES:` lines, those tests should add `-target x86_64-windows-msvc` to the flang invocation?
On platforms that didn't build the necessary libraries (e.g., a GNU system not explicitly configured to build a cross-compiler for that target), linking will likely fail. I don't know what `FileCheck` is doing. Can it cope with that?
