26 * We need the NULL macro and size_t typedef.
27 * On an ANSI-conforming system it is sufficient to include <stddef.h>.
28 * Otherwise, we get them from <stdlib.h> or <stdio.h>; we may have to
29 * pull in <sys/types.h> as well.
30 * Note that the core JPEG library does not require <stdio.h>;
31 * only the default error handler and data source/destination modules do.
32 * But we must pull it in because of the references to FILE in jpeglib.h.
33 * You can remove those references if you want to compile without <stdio.h>.
