   Actually, it would not matter.  By LRM 3.3.1(8), "Two type definitions
   always define two distinct types, even if they are textually identical."

   The "new" mechanism will generally be used when we want to put more 
   constraints on the new type than we had specified for the base type:

      type Weekday is new Day range Monday..Friday;

   This creates the type Weekday, which is distinct from (and incompatible
   with) the type Day.  If we wanted to make them distinct but compatible:

      subtype Weekday is Day range Monday..Friday;
