3362 the function can be called from resolve.c.

3365 already defined or if references were to another type.

3370 gfc_conv_function_call that coverts an expression for an aliased
3371 component reference to a derived type array into a temporary array

3373 actual argument for the procedure call and is copied back to the
3374 derived type after the call.
