This is the very old and known problem of inconsisties between the

I have a running gnat-2.00 on my Linux box. With a UUCP only access to
the internet I cannot upload it directly from my home machine.  Tomorrow
(Monday) morning I'll take 2 floppies to a friends machine, from where
I'll put it on sunsite and tsx-11.  After that I'll send out an
announcement in comp.os.linux.announce.
