	* fortran/trans-array.c (gfc_conv_expr_descriptor): Obtain the
	string length from the expression typespec character length value
	and set temp_ss->stringlength and backend_decl. Obtain the
	tree expression from gfc_conv_expr rather than gfc_conv_expr_val.
	Dereference the expression to obtain the character.
	* fortran/trans-array.c (gfc_conv_resolve_dependencies): Add string
	length to temp_ss for character pointer array assignments.
	* fortran/trans-expr.c (gfc_conv_component_ref): Remove the
	dereference of scalar character pointer structure components.
	* fortran/trans-expr.c (gfc_trans_subarray_assign): Obtain the
	string length for the structure component from the component
	expression.
	* fortran/trans-expr.c (gfc_conv_variable): Correct errors in
	dereferencing of characters and character pointers.
	* fortran/trans-expr.c (gfc_conv_function_call): Provide string
	length as return argument for various kinds of handling of return.
	Return a char[]* temporary for character pointer functions and
	dereference the temporary upon return.
