Sorry for not answering your question but...

In my experience I have found that if portablilty is a concern, then all
predefined types should be avoided.

Ada is one of the languages that lends itself the best to defining your own
types in a portable manner:

  type
    anInt32 is range -21474_83648 .. 21474_83647;

If you want to use a "vanilla" integer.

In many cases it is better to define a range that better describes your problem.

BTW: I've used the same type of definitions in 'C' ie:

typedef integer int32;
