        * libgfortran.h: New macros GFC_STD_OPT_*.
        * error.c (notify_std_msg): New function.
        (gfc_notify_std): Adjust such that it can handle combinations of
        GFC_STD_* flags in the 'std' argument, not just a single one.
        * match.c (match_arithmetic_if, gfc_match_if): Reject arithmetic if
        in Fortran 2018.
        (gfc_match_stopcode): Use GFC_STD_OPT_* macros.
        * options.c (set_default_std_flags): Warn for F2018 deleted features
        by default.
        (gfc_handle_option): F2018 deleted features are allowed in earlier
        standards.
        * symbol.c (gfc_define_st_label, gfc_reference_st_label): Reject
        nonblock do constructs in Fortran 2018.
