I'd suggest to have Yasamasa Suenaga included as one of the authors of this patch as we crossed working in parallel on this and he provided valuable input on build testing on WSL. I'm equally fine if the patch from Yasamasa in this list above is taken, in which case I can submit another patch for devkit.

For those interested in VS 2019 runtime binary compatibility details, please refer to section "VC Runtime in the latest MSVC v142 toolset is binary compatible with v140 and v141" in [1].
