I was finding that hard to believe, too, at least for CRC-32 (CRC-64
would take more code, so I'm not so sure about it).
Is that 64-bit code you pointed us to before actually a CRC, or
something else? It doesn't call itself a CRC, and I was having a hard
time extracting anything definite (like the polynomial) from all the
bit-pushing underbrush :-(
