  34  * of dialog was hacked to work with ncurses 1.9.9e, making it incompatible
  35  * with standard curses.  The simplest fix (to make this work with standard
  36  * curses) uses the wbkgdset() function, not used in the original hack.
  37  * Turn it off if we're building with 1.9.9e, since it just confuses things.
