Thanks for looking, they all make sense and I have addressed most.

With MinGW, you can cross build Windows binaries and run them with Wine,
like so

    ./pre-inst-env guix build --target=i686-w64-mingw32 hello
    /gnu/store/5lf701smnkq0wdg91jsyrmf5jnyz6i31-hello-2.10
    guix environment --ad-hoc wine -- wine /gnu/store/5lf701smnkq0wdg91jsyrmf5jnyz6i31-hello-2.10/bin/hello.exe

Ok.
