It looks good and I can compile `hello'; the traditional 32 bit version:

    ./pre-inst-env guix build --target=i686-w64-mingw32 hello

and now also

    ./pre-inst-env guix build --target=x86_64-w64-mingw32 hello

However, while the 32 bit still works for me, the 64 bit version does
not.  How is that for you?  Do you have any idea how to verify if the
x86_64 hello.exe is OK or how to debug that?

Possibly I'm even using wine wrong?

Other than that the patch looks fine.  It would be nice if we knew
wether the 64bit version can produce something useful, though.  Can
you/someone please shed some light on that?

Greetings,
