  There is a standard interface for such things: P1003.5 the POSIX Ada
Binding.  Not all OSes can support it, but it would be
counterproductive to have another "standard."

  On the other hand complete standard Ada bindings to APIs are a very
good idea, but don't belong in the Ada standard since they are OS
specific.  There exist good thin Ada bindings to most standard
operating systems.  Programs which use those thin bindings in
instead of the POSIX binding are of course less portable.
