Its not a Cygwin invention.  Its a MS one.  Check out the documentation
for open()/_open() on the MSDN.  They use the _O_BINARY flag.  Don't get me
wrong.  I hate text mode in all its forms.  Perhaps Cygwin could've forgone
its use here.  Maybe not.  However, doing so here follows the MS lead and
wasn't a Cygwin concoction.
