These are very similar.
They will be different if Integer'last < New_Int'last; in that case,
the compiler will report a compile time error.
They will have different base types if the base of Integer is 64 bits,
since New_Int will fit in 32 bits.
The only reason to derive an integer type from another integer type is
to ensure they have the same underlying representation.
