Hm, some of what you have here matches what I just pushed, but not all.

I just made the C code agree with what the SQL declarations for the
functions say.  I'm pretty dubious that the SQL declarations are entirely
sensible as to which values need to be of what width, but I'll leave that
decision for somebody who's been paying closer attention to the hash code.

Yeah, that's one possible answer.  We could also maintain two
expected-files for 32 bit v 64 bit, but I'm not sure it's worth
the trouble.
