344 when the bounds of the range are given by type conversions,
345 because in such a case there are distinct types involved and the

412 libgnat/s-valwch.ads: Change categorization of packages that
413 implement attribute 'Value from Pure to Preelaborate, to prevent
414 undesirable optimizations when the evaluation of the attribute
415 raises Constraint_Error, but subsequent use of the result of

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