ftp was the worst as far as porting changes from 1.3.2-X to 1.5. LOTS of 
stuff. It is entirely possible that I (a) missed something in forward 
porting old modifications, or (b) there was some new code in 1.5 that 
needed modification and I missed that.

That's why this is a test release. It works for me, but I've only got 
the one computer (* okay, I just got a vista machine last week, but I 
haven't even tried to install cygwin on it. Reading the horror stories...)

Right. I had no issues with inetd *itself*, running under the cyg_server 
(or sshd_server) account. It was (some of) the slave daemons that were 
troublesome -- but not all.  telnetd works (for me), for instance.  I 
remember that at least one of the r* cmds worked (for me), too -- except 
that unless LocalServer, .rhosts were not honored.

Oops. I was thinking of rlogind:

#define ROOT_UID    18
