So what are the details?  Which versions of Windows does MSYS2
support, and which ones does MinGW64 support?  And if MinGW64 is about
to drop Windows versions older than 8.1 soon, when will that happen?

I'm asking because I want to update our documentation with this
information, to avoid other users being surprised by these subtle
issues.

Thanks.
