I don't really agree with that, since systems often have a programming
mode in which longs are 32 bits even on a 64-bit system, just for
backward compatibility.

But I do think that the default in Andrew's patch should be to use
'unsigned long' on all systems, and specific systems should change
that default when appropriate.
