For one compilation unit, the type is an array of pointer to something, for example a record type and, for another compilation unit, the type is an array of ptr_type_node. That's because the "something" isn't even parsed by the compiler in the second case, so that you can change the implementation without recompiling all the clients. -- Eric Botcazou
