	* target-memory.h (gfc_target_interpret_expr):  Add boolean
	argument wether to convert wide characters.
	* target-memory.c (gfc_target_expr_size):  Also return length

	determined from the cl.
	(interpret_array):  Add argument for gfc_target_interpret_expr.
	(gfc_interpret_derived):  Likewise.

	* check.c:  Include target-memory.h.
	(gfc_calculate_transfer_sizes):  New function.

	gfc_simplify_transfer).
	* simplify.c (gfc_simplify_transfer):  Use
