582 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
583 libgnat/s-valwch.ads: Change categorization of packages that
584 implement attribute 'Value from Pure to Preelaborate, to prevent
585 undesirable optimizations when the evaluation of the attribute
586 raises Constraint_Error, but subsequent use of the result of
587 this evsaluation is removed by a subsequent optimization.

609 result of this enhancement, the internal tables declared using
610 Index_Table have a length closer to the real needs, thus
