-- Rewrite_Ins A flag set if a node is marked as a rewrite inserted
-- node as a result of a call to Mark_Rewrite_Insertion.
- -- Paren_Count A 2-bit count used on expression nodes to indicate
- -- the level of parentheses. Up to 3 levels can be
- -- accomodated. Anything more than 3 levels is treated
