"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>
