specify allow(dead_code) to be only on windows in the Args struct

[mbrubeck]

Instead of allowing dead code, should we make this field #[cfg(unix)] so it just doesn't exist on other platforms?

That would also be a nice option, if @w1kee wants to do that. It would require adjusting a few more places in the code.

I wasn't sure if #[cfg(unix)] can be used on things like fields in constructors but apparently that works too.

Thanks for your contribution!
