The ARG has looks at solutions to this problem for the upcoming
Amendment. The current proposal can be found in AI-254
(http://www.ada-auth.org/AI-SUMMARY.HTML is the AI index). Be aware
though that there is a substantial concern that this solution is too
complex for the problem.
(GNAT's solution only works because of the details of their
implementation. In general, you need a "fatter" than normal subprogram
access type in order to carry the additional information necessary to
make these calls and have them work. So the 'simple' solution of
adopting 'Unrestricted_Access can't be used.)
