Replacing ClearScreen and MoveCursor in ...\examples\screen.adb with:

  procedure ScreenClear;
  pragma Import(C, ScreenClear, external_name=>"ScreenClear");

  procedure ClearScreen renames ScreenClear;

  procedure ScreenSetCursor(row,col:in natural);
  pragma Import(C, ScreenSetCursor, external_name=>"ScreenSetCursor");

  procedure MoveCursor (To: in Position) is
  begin
    ScreenSetCursor(To.Row, To.Column);
  end MoveCursor;

makes the philosophers dine pleasantly on my non-ANSI screen
(though they don't clear the table when done).
Apparently it was the lack of "external_name=>..."s, rather
than a need to explicitly name a C library, that was giving
me troubles.  It appears I'll have to download more than the
minimum djgpp stuff to find answers to my other questions.
