Because of historical reasons, I have a number of Windows virtual
machines with 32-bit cygwin installed, including the cygwin sshd service.

It appears to be impossible to start a 64-bit bash session from a 32-bit
session. However, it there is a way to do this, the rest of the post is
not relevant.

During the transition to 64-bit cygwin, I would like to start a 64-bit
sshd service on a second port (2222, perhaps). When the transition is
fully complete, I will remove the 32-bit sshd service.

If I use the ssh-host-config program, it goes through, but tells me that
"Sshd service is already installed" and does not create another service.

How do I create a second service to run 64-bit sshd?
