True, that should be a flag

I wanted to check if you added the appropriate flag in Kalker 2.2.1, but unfortunately it was compiled without Windows 7 support, so I see the following error.

It seems the developers of Rust language betrayed users like me by removing such an option in their recent compiler. Shame on them! For example, C-based apps like xxhash can still be compiled and run without issues here.
