"Ref" is an implementation-defined attribute.  Ada 95 defines
a function for converting from integer to address in
the package System.Storage_Elements.  The following should
work on any Ada 95 compiler:

  Base_Addr : constant System.Address := System.Storage_Elements.To_Address
     (16#A000_0000#);
