telnet segfaults on Hurd

[Marcus Brinkmann]

Hi,

telnet segfaults on Hurd because of that:

TerminalFlushOutput()
{
#ifdef  TIOCFLUSH
    (void) ioctl(fileno(stdout), TIOCFLUSH, (char *) 0);
#else
    (void) ioctl(fileno(stdout), TCFLSH, (char *) 0);
#endif
}

TIOCFLUSH expects an (int *) as third argument.  The Hurd always requires
the arguments, as they are pasted to and from a server RPC.

Can't we better use tcdrain(fileno(stdout)) here anyway?

Marcus
