This is true. If I recall, when we worked on the port, we had some "checker" utilities that dumped out the struct name and size of all structures (sizeof(struct...)) on both platforms. The system was heavily based on memory mapped structs and serialization of those structs, so if a length didn't match, it was a bad sign. Fun times.
