	* tree.h (enum tree_index): Add TI_FILEPTR_TYPE.
	(fileptr_type_node): Define.
	* tree.c (build_common_tree_nodes_2): Initialize
	fileptr_type_node to ptr_type_node.
	* c-common.c (c_common_nodes_and_builtins): For C++, make
	fileptr_type_node a distinct type copy.
	* builtin-types.def (BT_FILEPTR, BT_FN_INT_CONST_STRING_FILEPTR,
	BT_FN_INT_INT_FILEPTR, BT_FN_INT_FILEPTR_CONST_STRING_VALIST_ARG,
	BT_FN_SIZE_CONST_PTR_SIZE_SIZE_FILEPTR,
	BT_FN_INT_FILEPTR_CONST_STRING_VAR): Add.

	BT_FN_SIZE_CONST_PTR_SIZE_SIZE_PTR, BT_FN_INT_PTR_CONST_STRING_VAR,
	BT_FN_INT_PTR_CONST_STRING_VALIST_ARG): Remove.
	* builtins.def (BUILT_IN_FPRINTF, BUILT_IN_FPRINTF_UNLOCKED,
