332 'Valid as a replacement for a range check on a discrete type
333 when the bounds of the range are given by type conversions,
334 because in such a case there are distinct types involved and the

400 libgnat/s-valrea.ads, libgnat/s-valuns.ads,
401 libgnat/s-valwch.ads: Change categorization of packages that
402 implement attribute 'Value from Pure to Preelaborate, to prevent
403 undesirable optimizations when the evaluation of the attribute
404 raises Constraint_Error, but subsequent use of the result of
405 this evsaluation is removed by a subsequent optimization.

427 result of this enhancement, the internal tables declared using
428 Index_Table have a length closer to the real needs, thus
429 avoiding the declaration of large arrays on 32-bit CCG targets.
