* flags.h (flag_bounds_check, flag_bounded_pointers): New extern decls.
* toplev.c (flag_bounds_check, flag_bounded_pointers): New flags.
(f_options): Add "bounded-pointers" and "bounds-check" entries.
* c-lang.c (lang_init_options): Set flag_bounds_check as "unspecified".
(lang_init): Set default for flag_bounds_check if still "unspecified".
