Remove traditional C constructs 3/n.

	* cvt.c (cp_convert_to_pointer, convert_to_pointer_force,
	build_up_reference, warn_ref_binding, convert_to_reference,
	convert_from_reference, convert_lvalue, cp_convert, ocp_convert,
	convert_to_void, convert, convert_force, build_type_conversion,
	build_expr_type_conversion, type_promotes_to,
	perform_qualification_conversions): Use C90 prototyping style.
	* decl2.c (grok_array_decl): Use boolean constant.
	(delete_sanity): Likewise.
	* typeck.c (build_unary_op): Likewise.
	* semantics.c (finish_switch_cond): Likewise.
	* parser.c (cp_parser_direct_new_declarator): Likewise.
	* init.c (build_new): Likewise.
