System.Address has always been a private type in GNAT, except perhaps
in the VMS version.

Why not upgrade to a more recent version?  3.1 is very old, and many
improvements have been made to GNAT since then.

It was common for Ada 83 compilers to use an integer type for Address,
but the Ada 95 RM recommends (but does not require) that it be a private
type.
