Unfortunately, a different group is using our Ada83 code with their Ada
compiler, and the only information I have is that they had to move rep
specs out of the private part of the package to get them to compile.
They
originally reported this to me as a bug in our Ada83 code/compiler,
which
confused me, and so I posted the question that started this thread.

I have forwarded the information you and others have posted here, and
they
are going to look at the intervening statements to see if they can see
what
is happening.  If I get more information, I will post it.
