3933 the function can be called from resolve.c.

3936 already defined or if references were to another type.

3941 gfc_conv_function_call that coverts an expression for an aliased
3942 component reference to a derived type array into a temporary array

3944 actual argument for the procedure call and is copied back to the
3945 derived type after the call.

3947 that is followed by a component reference.
