I have seen this failure before, and its usually a result of having
your CYGWIN environment variable including 'notty':

  http://www.cygwin.com/cygwin-ug-net/using-cygwinenv.html

Or maybe its the opposite.  I don't have access to my Cygwin system
right now, so I cannot check if I have notty, tty, or just ommitted
it entirely from my CYGWIN environment varible.  But I think that's
the issue.
