33 * Colors in ncurses 1.9.9e do not work properly since foreground and
34 * background colors are OR'd rather than separately masked.  This version
35 * of dialog was hacked to work with ncurses 1.9.9e, making it incompatible
36 * with standard curses.  The simplest fix (to make this work with standard
37 * curses) uses the wbkgdset() function, not used in the original hack.
38 * Turn it off if we're building with 1.9.9e, since it just confuses things.
