Blame Mark. ;) Seriously, everything else was automatically git-rebase- 
able, I've pushed a testable version:

Not sure what you're referring to above. I don't think I modified the  
type definitions, I went with what they were defined like. Most are  
long long as you say, but that's something I would like to be able to  
change in the future. Thus, I'm defining the cell types in term of  
POSIX integer types, using their PRI* macros to get away from the ll  
vs. l issue. Refactoring that into a separate patch now.

As for the client interface part, I take it that this still makes  
sense despite the ppc64 cell width discussion and will work towards
