Ignoring the shouting :-) ...

That command line assumes that the program will see \r\n
at the end of each line of input.  That is indeed the usual
line ending on Windows.  However!  Since it is not the usual
line ending on Posix (what Cygwin aims to be like), there
are various options/flags that can affect an internal
translation that effectively changes \r\n to \n, or
something like that.

Others will be able to supply the details more readily
than I, but I would look at the environment variable and
startup options to Cygwin around this point and see where
that leads you.
