Re: Problems with small windows and subprocesses on NT

With the recent big set of changes, I've had problems with ediff which probably will affect other things. There are two problems at least. When ediff is setting up the frame for the control window it creates it with a height and width of 1 and then changes it to the size it really wants. XEmacs crashes if any frame has a height less than 2. This happens because regenerate_window in redisplay.c gets a negative value for yend. In my case the pixel height of the window is 28 but window_bottom_gutter_height is 32 giving an available space of -4 pixels to display the contents of the frame.
