Thank you for the pointer.

I had seen the discussion and realise that some people need an int64.

But what I'm really interested in is the current state of affairs. I
wrote a little Vim script the other day where I assumed MAX_INT to be
2147483647. The help says that it is possible that MAX_INT is greater
than that. I don't know if that is true given the current code. I
believe it isn't, but I'm not sure.

Best,
