Hello,

This morning I updated cygwin.  At the same time, my Windows 7 (64bit)
was also updated.  Now I cannot ssh to my system.

I re-ran ssh-host-config and ssh-user-config.  I re-ran rebaseall with
default parameters (no -b 0x7...).

I can ssh to other systems.  But I cannot ssh to localhost

But the following fails:
>ssh -vv 977315 AT localhost
OpenSSH_6.0p1, OpenSSL 1.0.1c 10 May 2012
