568 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
569 libgnat/s-valwch.ads: Change categorization of packages that
570 implement attribute 'Value from Pure to Preelaborate, to prevent
571 undesirable optimizations when the evaluation of the attribute
572 raises Constraint_Error, but subsequent use of the result of
573 this evsaluation is removed by a subsequent optimization.

593 single letter literals and the Table built by the frontend would
594 have as many components as the length of the names string. As a
595 result of this enhancement, the internal tables declared using
596 Index_Table have a length closer to the real needs, thus
597 avoiding the declaration of large arrays on 32-bit CCG targets.
