I don't even think this behavior is POSIX compliant (but I >don't know how to check it). 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.
