Is this intended to replace #2457 #2458 #2459 #2460 #2461 #2462 #2463 #2464 #2465 and #2466?

Thanks for asking that, @loqs , as:

1. We have @brechtvl 's PR's queued up to process shortly
2. We specifically asked him to break the changes up as he did for fine-grained testing and regression analysis, and we would still not want to accept a monolithic change.

@aaye , can you please confirm, and let us know if you can follow the pattern of the previous PR's, and also let us know the scale of the fixes you made on top of the earlier work?

From what I can tell the main addition here is build system fixes for Windows? I did not test my changes on Windows, so getting that to work would be great. I can add additional changes to my PRs if needed (might be just #2466).

Closing this as we are finishing up work to incorporate @brechtvl 's PR's.
