PORTS: Please make sure I've done the right thing for/to your code. This patch adds a new winproc that lets the window port approve or cancel the suspend request - this should take care of the Mac Qt lockup issue. In addition, Unix suspend is restricted to accounts that can use the shell if SYSCF is defined.
