I was saying that the current Cygwin support is only for console devices:

      if (!ReadConsoleInput (h, &input_rec, 1, &nread))
        {
          __seterrno ();
          syscall_printf ("ReadConsoleInput failed, %E");
          return -1;            /* seems to be failure */
        }

This would not be appropriate for a non-console application like the
X server.

If someone wants to add generic keyboard and mouse support for a Windows
app, then that would be appropriate.
