Looks good to me overall. I suggested using conditional compilation to reduce footprint for non-windows targets.

Also, I've been in the process of adding some basic CI testing (#1), so it probably makes sense to add a new CI job that runs the crate unit tests in the windows-latest environment as well. It has MSVC 17.1 pre-installed, so everything should hopefully work out of the box.

Nice, thanks!

Edit: MinGW dlltool is not found on windows-latest, which leads to partial unit test failures. Maybe these tests can be made conditional on #[cfg(unix)] or you could figure out how to install MinGW binutils via MSYS2 pacman.

Since mingw64 is already tested on Linux, I choose to add #[cfg(unix)]s.

Everything seems fine, thank you!

I'll release it as 0.2.1 in a few days, after I figure out how to publish crates from GitHub Actions.
