cygwin 3.0.1-1 breaks my sshd install

[scowles@ckhb.org]

i can confirm the same behaviours on a 3.0.0 system.  i've done several checks 
and have been unable to find the source of the problem.  ssh -vvv shows that the 
connection proceeds all the way through the connection process, sends the 
appropriate key tokens, then the server abruptly closes the connection. all 
accounts on the system show the same results.

my 2.11.1 system, with identical ssh[d]_config files has no such problems.

on both systems, all relevant files and directories have correct owners and 
permissions.
