	* gcc/c-family/c-pretty-print.h (pp_c_flag_gnu_v3): New enumerator.
	* gcc/c-family/c-pretty-print.c (pp_c_specifier_qualifier_list): Check
	it at both the start and end of the function.
	* gcc/cp/error.c (dump_decl): Check pp_c_flag_gnu_v3.
	(decl_as_dwarf_string, lang_decl_dwarf_name): New functions.
	(lang_decl_name): Handle namespace decls.
	* gcc/cp/cp-tree.h: Declare decl_as_dwarf_string, lang_decl_dwarf_name.
	* gcc/cp/cp-lang.c: Call them.
