707 'Valid as a replacement for a range check on a discrete type
708 when the bounds of the range are given by type conversions,

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

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