    case OPT_Wc___compat:
      if (!opts_set->x_warn_enum_compare)
        handle_generated_option (opts, opts_set,
                                 OPT_Wenum_compare, NULL, value,
                                 lang_mask, kind, loc, handlers, true, dc);
      if (!opts_set->x_warn_enum_int_mismatch)
        handle_generated_option (opts, opts_set,
                                 OPT_Wenum_int_mismatch, NULL, value,
                                 lang_mask, kind, loc, handlers, true, dc);
      break;


Are handled correctly but not Wjump-misses-init.


Wenum-compare from c-family/c.opt:
```
Wenum-compare
C ObjC C++ ObjC++ Var(warn_enum_compare) Init(-1) Warning LangEnabledBy(C
ObjC,Wall || Wc++-compat)
Warn about comparison of different enum types.
