(Implementation_Unit,
-- Unit from predefined library intended to be used only by the
-- compiler generated code, or from the implementation of the run time.
-- Use of such a unit generates a warning unless the client is compiled
-- with the -gnatg switch. If we are being super strict, this should be
-- an error for the case of Ada units, but that seems over strenuous.
Not_Predefined_Unit,
-- This is not a predefined unit, so no checks are needed
Ada_95_Unit,
-- This unit is defined in the Ada 95 RM, and can be freely with'ed
-- in both Ada 95 mode and Ada 05 mode. Note that in Ada 83 mode, no
-- child units are allowed, so you can't even name such a unit.
Ada_05_Unit);
-- This unit is defined in the Ada 05 RM. Withing this unit from a
-- Ada 95 mode program will generate a warning (again, strictly speaking
-- this should be an error, but that seems over-strenuous).
function Get_Kind_Of_Unit (U : Unit_Number_Type) return Kind_Of_Unit;
-- Given the unit number of a unit, this function determines the type
-- of the unit, as defined above.
