CC #6038

This works with nightly, but that has other issues (proc macros not working).

I have this problem on windows now: use std::os::windows::io::RawSocket; was not working. However, after reading #6038, I figured adding cfg-if in the dev-dependencies (or regular dependencies but I don't really need that) would make it work again. Before that I though naively that rust-analyzer was not getting the right target or something and set "rust-analyzer.cargo.target": "x86_64-pc-windows-msvc". I went searching through the github issues after I realized the problem was something else.

I just removed those settings and the cfg-if and the error comes back. Adding just the cfg-if is enough to get it working again.

Also happened on nightly Rust Analyzer with rustc 1.53. Fixed by updating to rustc 1.54.

I have been used rustc 1.54 and have the same problem, but after I updated to rustc 1.55(the latest version) and it was fixed.

This has been fixed (for some time, I guess).
