            warn_missing_include_dirs and move before caller.

            (gfc_cpp_init_0): ... here.
            (gfc_cpp_post_options): Call gfc_cpp_init_cb.
            (cb_cpp_diagnostic_cpp_option): New. As implemented in c-family
            to match CppReason flags to -W... names.

            (add_path_to_list): ... here, which came before cmdline process=
