Actually, 2 ** 31 * Whatever'Size / 8 bytes.

However, this is not technically true. The language does not specify how such 
things are stored. Some compilers (Janus Ada, for example) only use enough 
memory to store the current value of the object; others (GNAT, for example) 
allocate enough memory for the largest possible value. Of course, portable code 
has to work with both.
