* mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for

	compiler generated tag names.
	* mdebugread.c (parse_type):  Handle cross references to qualified
	aggregate types.
	* valops.c (value_struct_elt):  Improve error message if the
	address of a method is requested from an object instance.
	* valops.c (search_struct_method):  Make name_matched non-static
	to get it initialized correctly.
