The implementation in question supports 32-bit integers on all targets,
but "Integer" is 16-bits ("Long_Integer" is 32-bits). On some targets,
32-bit operations are more expensive; on 32-bit targets like the
Pentium, that's not even true, but "Integer" is 16-bits for
interoperability with the older targets.

Don't use Integer if you (may) need a range beyond 32767. (Which, BTW,
is a significant complaint of mine about the design of the standard
string libraries, but enough of that...)
