No, Interfaces.C.Extensions is non portable, so almost no Ada code out there is using it. As I said, existing Ada code is using System.Address all the time, so requiring any code change in this area is just a non starter. We'd rather require that people don't use LTO with Ada rather than tell them to use Interfaces.C.Extensions, that would be more constructive :-) Arno
