  Timer handling; UNIX has no application timer support so we'll have to
  make our own from scratch.

  NOTE: These functions are for internal use. TQObject::startTimer() and
	TQObject::killTimer() are for public use.
	The TQTimer class provides a high-level interface which translates
	timer events into signals.

  qStartTimer( interval, obj )
	Starts a timer which will run until it is killed with qKillTimer()
	Arguments:
	    int interval	timer interval in milliseconds
	    TQObject *obj	where to send the timer event
	Returns:
	    int			timer identifier, or zero if not successful

  qKillTimer( timerId )
	Stops a timer specified by a timer identifier.
	Arguments:
	    int timerId		timer identifier
	Returns:
	    bool		TRUE if successful

  qKillTimer( obj )
	Stops all timers that are sent to the specified object.
	Arguments:
	    TQObject *obj	object receiving timer events
	Returns:
	    bool		TRUE if successful

      IRIX, on the other hand, expects a size_t, which is 64-bit on
      64-bit machines.
