Norman says
"There is nothing in Ada-95 to prevent vendors who provided these signed
types with modular behavior in their Ada-83 compilers from also providing
them in their Ada-95 compilers, in addition to the modular types required
by the Ada-95 standard. Such types are redundant in the presence of
Ada-95 modular types, but provide a path for customers to migrate their
legacy Ada-83 code to Ada 95.
"
Indeed, for example, in the VMS port of GNAT, we have added a pragma
Extend_System that allows you to add implementation specific features
to package System, and we use this feature to allow a user to put all
the standeard DEC unsigned support into system (as well as all the other
DEC system stuff).
