26 | "defs.h" should be included first. Unfortunatly some systems | |
27 | (currently Debian GNU/Linux) include the <stdbool.h> via <curses.h> | |
28 | and they clash with "bfd.h"'s definiton of true/false. The correct | |
29 | fix is to remove true/false from "bfd.h", however, until that | |
30 | happens, hack around it by including "config.h" and <curses.h> | |
31 | first. */ | |
