It is not a Cygwin problem. It's a MSVCRT runtime problem. The
runtime checks isatty to determine the buffering of stdout (this is a
standard C thing to do), and Cygwin terminals do not show up as
consoles.
If the underlying device is really a Windows console, of course,
there's no problem. But Cygwin SSH ptys, for example, are not
Windows consoles.
