First, the code is/should be also allowed for -std=legacy (GFC_STD_LEGACY).
Secondly, the point is not that GFC_STD_GNU and GFC_STD_F2008 are same (they
obviously aren't), but that
having (compile_options.allow_std | GFC_STD_F2008) != 0
=> implies (compile_options.allow_std | GFC_STD_GNU) != 0
which is a property of "allow_std". See gcc/fortran/options.c:
case OPT_std_f2003:
gfc_option.allow_std = GFC_STD_F95_OBS | GFC_STD_F77
| GFC_STD_F2003 | GFC_STD_F95 | GFC_STD_F2008_OBS;
case OPT_std_f2008:
gfc_option.allow_std = GFC_STD_F95_OBS | GFC_STD_F77
| GFC_STD_F2003 | GFC_STD_F95 | GFC_STD_F2008 | GFC_STD_F2008_OBS;
case OPT_std_gnu:
set_default_std_flags ();
break;
