2007-12-22  Jan Kratochvil  <jan.kratochvil@redhat.com>

	* dwarf2read.c (scan_partial_symbols partial_die_parent_scope)
	(add_partial_symbol, pdi_needs_namespace, process_die)
	(is_type_tag_for_partial, load_partial_dies, new_symbol)
	(read_type_die, determine_prefix): Extend the current code of
	`DW_TAG_class_type' also for `DW_TAG_interface_type'.

2007-12-28  Jan Kratochvil  <jan.kratochvil@redhat.com>

	* dwarf2read.c (fixup_partial_die): Provide full
	`DW_TAG_class_type'-type backing for `DW_TAG_interface_type', even for
	namespaces which should not apply for Java `DW_TAG_interface_type'.
