I do NOT know all about it. I did manage to cross-compile the easy
bits with mingw64, but that did not include e.g. XeTeX.

I opted for cross-compiling, because a native compile is an order of
magnitude slower.

I did build a mingw64 toolchain based on ucrt (see e.g.
https://mingwpy.github.io/ucrt.html and
https://github.com/Zeranoe/mingw-w64-build) but I am not sure
anymore what did and did not work with this toolchain.

Since Akira provides our Windows binaries and Luigi has a working
mingw setup, I am not working on this anymore.
