cp-tree.h (char_type_p): New function.

	* cp-tree.h (char_type_p): New function.
	* decl.c (init_decl_processing): Don't initialize
	signed_wchar_type_node or unsigned_wchar_type_node.
	(complete_array_type): Handle brace-enclosed string-constants.
	* rtti.c (emit_support_tinfos): Remove #if 0'd code.
	* tree.c (char_type_p): New function.
	* typeck2.c (digest_init): Use char_type_p.
