See 10.1.4(3). Of course it doesn't mean--or have anything to do 
with--object files.

See, this is why you are a troll. RM 10.1.4(5) is completely clear on 
this issue.

Let's see.  You pretend to be an expert on Ada.  And every time you open 
your mouth in this newsgroup you reveal the depths of your ignorance.

If you had been paying attention, you would have noticed that they were 
considered for inclusion.  I was one of the people who commented on that 
and convinced everyone that the current model did not need fixing. 
There are different implementations of that model, and I certainly agree 
that the work that Robert Dewar and Richard Stallman (rms) plus others 
put into developing the GNAT implementation of that model were also 
played a big part.

I know the history.  I have been involved in the development and 
standardization of Ada since 1981.  I am not perfect and I don't claim 
to be.  But you may have noticed that if I make a mistake in a posting 
here I acknowledge it gracefully.  You need to learn how to do that.

I apologize to every other comp.lang.ada reader for once again being 
tempted into responding to this troll.
