The standard could certainly have mandated a reasonable minimal range. There
were some such range requirements added to Ada 83, but they are so pathetic
that they are counter-productive, since they imply that it is perfectly
OK to produce a crippled compiler with minimal range capabilities (e.g.
Integer must be at least 16 bits -- wonderful!)
It certainly seems absurd to me if any general purpose Ada compiler does
not implement 64-bit integer arithmetic on all targets at this stage.
