The repository now includes a file nt/INSTALL.W64 which should cover
the same turf, and be at least as accurate as the MSYS2 instructions,
since INSTALL.W64 is maintained as part of Emacs.

Thanks for testing.  It is important that the original use case that
prompted this bug report will also be checked, as I understand it is
more complicated.  Can you ask the relevant people to try that?

If you can afford that, yes, it would help to see that this commit
fixed the issue.

Thanks.
