Oh silly bot, this is really a libs thing. Just with a bit of cranelift sprinkled on top, r? libs |

This is a workaround for older mingw `synchronization` import library not working on at least some system.

Use raw-dylib for Windows synchronization functions Fixes rust-lang#123999 by using the raw-dylib feature to specify the DLL to load the Windows futex functions from (e.g. [`WaitOnAddress`](https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitonaddress)). This avoids reliance on the import library causing that issue. With apologies to `@bjorn3,` as it's currently necessary to revert this for cranelift.

I'm nominating this for a beta backport, even though this isn't technically a Rust issue. See linked issue for more but the short version is that the windows-2019 github action runner comes with a years old mingw that has a bug which will prevent windows-gnu std from working if compiled on that machine. This PR works around the bug. It's a small PR so I think it's worth it to make sure that stable works out of the box on windows-2019. Note that the windows-latest runner isn't affected. |
