$ echo $?
255

I get the same message from a DOS command shell when I cd to /cygwin/bin and execute ssh directly.

I've also attached the output of a cygcheck which did show a few issues I was not aware of and which I will work on 
correcting this weekend; but which shouldn't affect ssh's operations (as far as I am aware).
