 * Colors in ncurses 1.9.9e do not work properly since foreground and

 * background colors are OR'd rather than separately masked.  This version

 * of dialog was hacked to work with ncurses 1.9.9e, making it incompatible

 * with standard curses.  The simplest fix (to make this work with standard

 * curses) uses the wbkgdset() function, not used in the original hack.

 * Turn it off if we're building with 1.9.9e, since it just confuses things.
