Subject: [PATCH] Prevent DNS leaks on Windows 10

- This will generate a warning in unsupported environments.
- This will not work if the client is using an OpenVPN version lower
than 2.3.9
- For OpenVPN 2.3.3+, ignore-unknown-option could be used instead of
setenv opt to prevent a warning.

TL;DR: upgrade to the latest OpenVPN on Windows, ignore the warning
elsewhere.

Thanks a lot for your continuous work on OpenVPN, @ValdikSS.
