This is a Gnat specific question, so I'm sorry.

I'm getting a circular withing error during binding (Windows NT, Gnat3.11),
here's the error:
   error: elaboration circularity detected
   info:    "dgs (body)" must be elaborated before "dgs (body)"
   info:       reason: Elaborate_All probably needed in unit "dgs (body)"
   info:       recompile "dgs (body)" with -gnatwl for full details
   info:          "dgs (body)"
   info:             is needed by its spec:
   info:          "dgs (spec)"
   info:             which is withed by:
   info:          "mfd_pkg (spec)"
   info:             which is withed by:
   info:          "symbols (body)"
   info:             which is needed by its spec:
   info:          "symbols (spec)"
   info:             which is withed by:
   info:          "dgs (body)"
   gnatmake: *** bind failed.

Now, I checked the documentation (gnat_ug), and it had a section very
specific to this (What to do if the default
elaboration behavior fails).  However, I tried a couple of their fixed to no
avail. I originally had:

   with Symbols ;
   pragma Elaborate (Symbols) ;

in DGS.ADB.  I changed this to "pragma Elaborate_All (Symbols) ;", but it
didn't work.  I also tried passing in the
"-bargs -f" during gnatmake, and that didn't work either, nor did -gnatE
have any effect.  I haven't yet tried
re-arranging the code to remove this "Circular withing" (I personally don't
think it truely is), because it will be time
consuming.  If anyone has any suggestions, I'd appreciate it.  Thanks...
