/* FIXME: cagney/2002-02-28: The GDB coding standard indicates that

   "defs.h" should be included first.  Unfortunatly some systems

   (currently Debian GNU/Linux) include the <stdbool.h> via <curses.h>

   and they clash with "bfd.h"'s definiton of true/false.  The correct

   fix is to remove true/false from "bfd.h", however, until that

   happens, hack around it by including "config.h" and <curses.h>

   first.  */
