This is entirely irrelevant as there are only two possible cases.   The 
code is written to handle both cases transparently, and does.

$ netstat -an | grep 2402
tcp        0      0* 
tcp6       0      0 ::1:2402                :::* 

$ netstat -an | grep 2401
tcp6       0      0 :::2401                 :::* 

cvsnt doesn't just cater for a couple of OSs - the commercial builds run 
on all sorts of environments and the code to handle these cases has to 
be (and is) robust.

I can see absolutely no reason why anyone would want to do this.  The 
config is there to change the port in case there's a conflicting 
application.  Changing the address only makes sense for multi-server 
configurations and those are pretty rare in themselves.

The only thing missing from cvsnt is the -4 and -6 command line options 
that are in evs.
