3249 that is not a dummy argument.

3332 the function can be called from resolve.c.

3335 already defined or if references were to another type.

3340 gfc_conv_function_call that coverts an expression for an aliased
3341 component reference to a derived type array into a temporary array

3343 actual argument for the procedure call and is copied back to the
3344 derived type after the call.

3346 that is followed by a component reference.
