What's the output of rustc --version --verbose?

Is your Z: a network drive? If so, I think this is probably rust-lang/rust#54216, which will hopefully be fixed once Rust upgrades to LLVM 13. You could try setting your temp dir to a local path while you run cargo install. If your case is different, then please file a new Rust bug with those details.

Either way, there's nothing autocfg can do about it. This crate just happens to be one of the first things that gets compiled in many builds, since it's needed by build scripts.
