I asked you first since you're a gatekeeper.  I plan to email Dennis
Jones to develop a consensus for consideration.

Double checking, who else beyond the lists should be solicited?

Not yet (I'm avoiding lost time on unacceptable options) but that's why
I asked.  My preliminary reading looks promising so far.

Yes, Windows NT supports the DOS API but it still imposes constraints.
The 8.3 size limit and upper case only for file names being the worst.

I assume the directory name "windows-NT" implies a minimum API level
which has to be the Win32 API.  The code in "windows-NT" seems to rely
heavily on the NT POSIX layer but it's not fully compliant and I expect
Microsoft will deprecate or drop it at some point.

Right now I'd lean towards using the Win32 API directly and avoiding
the NT POSIX layer but that is NOT a proposal for the CVS project.

I hope MinGW lives up to it's initial promise.
