No. In the first place, 2 type declarations always create 2 distinct
types, even if everything is identical except the type name.
New_Int is an integer type with a range of 1 .. 1_000_000. New_Int'Base
will be chosen by the compiler.
New_Int1 is an integer type with a range of 1 .. 1_000_000.
New_Int1'Base has the same representation as Integer. Thus New_Int1 is
similar to
subtype New_Int1 is Integer range 1 .. 1_000_000;
except that type New_Int1 cannot be mixed with Integer, and subtype
New_Int1 can.
If you have a compiler for a 64-bit processor, Integer is probably a
64-bit type, and New_Int1 will be, too. New_Int'Base will probably be a
32-bit type.
Note how much easier it is to read one million when it's written with
underscores.
