My understanding of this was that my original patch which added
getLong included the ntohl() calls being added here, but should not
have. It had worked fine for me on Sparc (ntohl -> noop), but broke on
Intel, so bert removed those calls before applying the patch. As far
as I can see the code is correct as it stands.

Apologies for any confusion caused.
