I don't use it but there is one difference that I actually reported
years ago:
http://sourceware.org/bugzilla/show_bug.cgi?id=513
and I mentioned it again in
http://cygwin.com/ml/cygwin-patches/2009-q4/msg00144.html
and
http://cygwin.com/ml/cygwin-patches/2009-q4/msg00155.html
- later I tried to debug again and saw that with CYGWIN=tty, one
fhandler_console object drives console I/O whereas with CYGWIN=notty 3
objects are created (for stdin, stdout, stderr). This is the reason for
the cursor position response code getting lost because it is pushed into
the wrong fhandler_console object. I tried to patch it but it got all
messed up so I didn't post anything then.
