Michael's message wasn't meant as literal code. A compiler compiled for
x86_64 will have sizeof(pointer)=8, but the pointer size of the target
architecture (AFAIK called "aint" in the compiler, but I'm not sure
currently) might be different from that, so inside the compiler One should
know exactly which kind of Pointer one is talking about.
