    Huh , I know some of those third-part realtime extensions for NT, but
still Ada real time extension won't make use of it ??? Like even if RT
extension allow 256 priority levels instead of only 32 available on NT, in
GNAT I will have something like Priority'Last = 32 ?? Is there any RT
extension for NT which allow to use Ada Annex D with it ?
