Well, yes, maybe it is an untidiness. I don't think it would make any
difference on most (all?) 32-bit systems, where long int is usually the
same as int. It might affect 16-bit systems where int and long int are
different. If I changed it, it would be an incompatible change for
16-bit systems, but on the other hand, the sort of values you put in
there wouldn't fit into 16 bits anyway. So in a way it is a bug fix (for
16-bit systems).

Therefore, I think I will make the change when I next work on PCRE.

Thanks for making the point.
