| This makes a juncture point, which is like a symlink but only works on directories. I would assume the reason it's used here is because it works without special permissions or developer mode being enabled. Perhaps std should expose a safe API. |

Avoid UB in the Windows filesystem code in... bootstrap? This basically a subset of the changes from rust-lang#101171. I didn't think to look in src/bootstrap for more windows filesystem API usage, which was apparently a mistake on my part. It's kinda goofy that stuff like this is in here, but what are you gonna do, computers are awful. I also added `winbase` to the `winapi` dep -- I tested this in a tmp crate but needed to add this to your Cargo.toml -- you `use winapi::stuff::winbase` in this function, but are relying on something else turning on that feature.
