compat warning messages

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

I just upgraded a machine from 5.99.6 to 5.99.7.  I see a large pile of
warning messages about missing symbols:

Where are all of these coming from, and how can I make them stop?

Now -- with the exception of Linux (which I thought I did have enabled),
I don't need any of these binary compatibility programs.  Something seems
to be concerned, though.  I don't see anything in UPDATING about it, though
I recall messages about COMPAT going by on current-users.
