Long_Integer may already be defined in your compiler; the ARM says
it's an optional type, but I think most compilers define it (at least,
if there are assembly instructions which would manipulate such an
integer directly).

If not, you can define it this way:

type Long_Integer is range -2_147_483_647 .. 2_147_483_647

Mind you, I think this will only work if there already is a 32 bit
integer type in your compiler, and if so it's probably already called
Long_Integer.
