Hmm how hard would it be to use the MinGW libraries like DMD is 
doing as a fallback since 2.079?

https://dlang.org/changelog/2.079.0.html#lld_mingw

Rainer's excellent work on this is mostly found in 
dlang/installer:

https://github.com/dlang/installer/blob/build-mingw-libs/windows/build_mingw.bat
https://github.com/dlang/installer/blob/build-lld/windows/build_lld.bat
https://github.com/dlang/installer/pull/281
https://github.com/dlang/dmd/pull/7500

(mingw and lld are separate branches, s.t. they aren't built on 
every AppVeyor run)
