-- Used to compute Enum'Image (Str) where Enum is some enumeration type
-- other than those defined in package Standard. Names is a string with
-- a lower bound of 1 containing the characters of all the enumeration
-- literals concatenated together in sequence. Indexes is the address of
-- an array of type array (0 .. N) of Interfaces.Integer_16, where N is the
-- number of enumeration literals in the type. The Indexes values are the
-- starting subscript of each enumeration literal, indexed by Pos values,
-- with an extra entry at the end containing Names'Length + 1. The reason
-- that Indexes is passed by address is that the actual type is created on
-- the fly by the expander. The desired 'Image value is stored in S
-- (1 .. P) and P is set on return. The caller guarantees that S is long
-- enough to hold the result and that the lower bound is 1.
