GCC 4.0 GetKeys() and BigEndianLong for Intel

Ouch!
I guess it's way to late to get it changed now, but that strikes me as exactly the sort of thing that will be a pain.
There's no real reason *why* it has to be a struct rather than just a long, I guess, but it forces us to use target specific code and to know the detail of the underlying implementation. Seems a shame. If it was just a long, we could simply call htonl()  (for example) and get the Right Thing on *any* architecture.
Oh well.
