To recap:
- Cygwin can, but it needs special setup. This setup is not trivial:
if you intend to use same Windows Mapped Network Drive. If you use
mount(1), you lose Windows File Manager Integration because paths
are no longer the same.
- Emacs can't rely on UID, GID on Cygwin to be correct.

Yes, Windows NT EMacs port works fine. No problems
- File on remote drive are not marked read-only
- File on remote drive are written without asking.

Yes.

It's too complex, and doesn't work with multiple Samaba severs that
would use all different GID, UIDs for the same user name, and I cannot
get right UIDs and GIDs installed ... too many issues.
I can work just fine under Cygwin without these GID, UIDs set. But I
can't use Emacs effectively.
I would expect there to be at least an option to control these
pre-emptive confirmation questions. Without any control, the situation
is a nightmare.
Compare:
confirm-kill-emacs
dired-no-confirm
message-kill-buffer-on-exit
vc-suppress-confirm
