portable file copying in Ada

[self@lafite.ics.uci.edu (John Self)]

Is it possible to write a portable procedure to copy non-text files in
Ada?  What should I use for the element type when I instantiate
SEQUENTIAL_IO?   The procedure I want to write takes two file names,
and copies the contents of the file named by the first to the second.
I will not do any interpretation of the file, I just need to make an
exact copy of the contents.  If the underlying operating system is
based on files containing bytes, then I want to copy bytes.  If it
uses packed 27 bit words I'd be happy to copy those.
