Why are DW_TAG_{typedef,base_type,subrange_type} in static symbol list?

Why are DW_TAG_{typedef,base_type,subrange_type} in static symbol list?

Hi.

Does anyone understand why this code in dwarf2read.c adds typedefs,
base_type, subrange_type to objfile->static_psymbols and not
objfile->global_psymbols?
At least for c++ wouldn't a better location be global_psymbols?
[Similarly to how DW_TAG_{class,structure,...} types are handled?]

add_partial_symbol:

    case DW_TAG_typedef:
    case DW_TAG_base_type:
    case DW_TAG_subrange_type:
      add_psymbol_to_list (actual_name, strlen (actual_name),
			   built_actual_name,
			   VAR_DOMAIN, LOC_TYPEDEF,
			   &objfile->static_psymbols,
			   0, (CORE_ADDR) 0, cu->language, objfile);
      break;

vs:

    case DW_TAG_class_type:
    [...]
      add_psymbol_to_list (actual_name, strlen (actual_name),
			   built_actual_name,
			   STRUCT_DOMAIN, LOC_TYPEDEF,
			   (cu->language == language_cplus
			    || cu->language == language_java)
			   ? &objfile->global_psymbols
			   : &objfile->static_psymbols,
			   0, (CORE_ADDR) 0, cu->language, objfile);


And similarly in new_symbol_full:
[these two cases should at least be combined]

	case DW_TAG_typedef:
	  SYMBOL_CLASS (sym) = LOC_TYPEDEF;
	  SYMBOL_DOMAIN (sym) = VAR_DOMAIN;
	  list_to_add = cu->list_in_scope;
	  break;
	case DW_TAG_base_type:
        case DW_TAG_subrange_type:
	  SYMBOL_CLASS (sym) = LOC_TYPEDEF;
	  SYMBOL_DOMAIN (sym) = VAR_DOMAIN;
	  list_to_add = cu->list_in_scope;
	  break;

vs:

	case DW_TAG_class_type:
	[...]
		list_to_add = (cu->list_in_scope == &file_symbols
			       && (cu->language == language_cplus
				   || cu->language == language_java)
			       ? &global_symbols : cu->list_in_scope);
