That's a wrong memory, GNAT has always allocated the maximum size. Any
other implementation is very error prone and extremely complex, and
also requires implicit heap allocation which we avoid in GNAT. Really
allocating the maximum is the only feasible implementation, and it is
the only one used by current ADa 95 implementations as far as I know.
