RM-13.4(8) *requires* the internal codes to be 0, 1, 2...
if no representation clause is given.
So there's never a need to say "for Enum_Type use (0, 1, 2, 3);" --
that's the default.  It is not implementation dependent.

And of course the position numbers always start at 0, no matter what
the representation is.
