sshd 3.9p1 under Reliant Unix 5.45: getpeername: Operation not supported on transport endpoint

[Robert Dahlem]

The following is special to sshd 3.9p1 under ReliantUnix 5.45. It does 
not occur under ReliantUnix 5.43 nor under Solaris 5.8:

	`pwd`/sshd-3.9 -e -D -d -d -d

Now connecting from outside
	[...]
	debug1: inetd sockets after dupping: 3, 3
	debug1: get_port() calls get_sock_port(3)
	debug1: getpeername failed:
		 Operation not supported on transport endpoint

lsof proves FD 3 is an established TCP connection.

It does not occur when sshd is started with -r to prevent usage of the 
new re-exec mechanism.

I'm pretty sure it's something weird with ReliantUnix 5.45 concerning 
inherited sockets.

Anyone here having a pointer where to start the chase?
