The point is that in Pascal they are NOT different types, so if one wants to
mirror the semantics of the Pascal program - which is presumably the reason
for translating it - one must do as I say.

Even writing afresh in Ada, it is very unlikely indeed that one would want
EVERY subrange to be a separate type.
