Subject: [PATCH] Unbreak the GNUstep build.

* src/nsterm.m ([EmacsBell init]): In GNUstep, don't use the
predefined "caution" image. Add trace.
(x_set_window_size): Remove unused variables `cols' and `rows'.
(ns_draw_fringe_bitmap): Exclude assignment of `fromRect' when
GNUstep is used.
([EmacsView updateFrameSize:]): Remove unused variable `win'.
([EmacsWindow zoom:]): Remove unused variable `f'.
