My point is that since they are different types, the language itself
will need to provide some mechanism for doing this type conversion
_anyway_. 'int' and 'long' are used throughout the backend APIs, so I
don't see the gain in only converting the SPI functions over to using
int32/int64.

Well, the executor allows you to specify a 64-bit count on platforms
where "long" is 64-bit, and a 32-bit count otherwise. ISTM the most
straightforward way to expose this to clients is to just make the
parameter a "long". As I said before, we may or may not want to change
the executor itself to use a constant-sized type, but as a matter of
interface definition, I think using "long" makes the most sense.

BTW, patch applied to HEAD.
