Re: -ve values in enumeration rep clauses.

[dewar@cs.nyu.edu (Robert Dewar)]

Darrel asked about an interesting problem where enuemration literals are
not ordered. This is of course illegal, as GNAT will be happy to inform you:

     1. procedure w is
     2.  type A_Type is
     3.         ( A, B, C );
     4.  for A_Type use
     5.         (
     6.           A => -1,
     7.           B => -2,
                  |
        >>> enumeration value for "B" not ordered

     8.           C => -3
                  |
        >>> enumeration value for "C" not ordered

     9.         );
    10.  for A_Type'Size use 8;
    11. begin
    12.    null;
    13. end;
