You're probably running into this: https://github.com/rust-lang/cargo/issues/7058

`cargo vendor` will download dependencies and dev dependencies for all platforms, which leads to a lot of unused code being pulled in. In this case, the Windows API and Microsoft compiler wrappers.

In this instance, during the build process "tempfile" is used as a dev-dependency, which has a runtime dependency on windows-sys when compiling Windows binaries. I'm not entirely sure why (commenting it out in Cargo.toml doesn't seem to break the build).

After commenting it out and manually removing the spurious Windows API files as well as the unrelated packages (`cd vendor; rm -rf ctor diff output_vt100 pretty_assertions proc-macro2 quote syn unicode-ident yansi win*`), I get the following results:
