I would expect that I would have to be pretty careful about how things are
written when handling unsigned integers > signed max_int. I would not want to
do the arithmetic as signed integers and only store an unsigned integer.

For the time being most problems with these numbers will be limited to those
who have Ada compilers which have 32 bit integers as their largest integers.
Most disks bought these days are currently larger (in bytes) than the largest
integer available on these systems. Some of our systems generates files which
are larger than can be expressed with a signed 32bit integer. For the curious:
these are Oracle export files.

I am relieved that gnat allows 64 bit integers. That will keep my use of
unsigned integers out of trouble for the time being (I'm currently mainly 32
bit).
