    ------------------------
 
-   --  The following type includes an enumeration entry for each runtime unit.
-   --  The enumeration literal represents the fully qualified name of the unit,
-   --  as follows:
-
-   --    Names of the form Ada_xxx are first level children of Ada, whose name
-   --    is Ada.xxx. For example, the name Ada_Tags refers to package Ada.Tags.
-
-   --    Names of the form Ada_Calendar_xxx are second level children of
-   --    Ada.Calendar. This is part of a temporary implementation of delays;
-   --    eventually, packages implementing delays will be found relative to
-   --    the package that declares the time type.
-
-   --    Names of the form Ada_Interrupts_xxx are second level children of
-   --    Ada.Interrupts. This is needed for Ada.Interrupts.Names which is used
-   --    by pragma Interrupt_State.
-
-   --    Names of the form Ada_Real_Time_xxx are second level children of
-   --    Ada.Real_Time.
-
-   --    Names of the form Ada_Streams_xxx are second level children
-   --    of Ada.Streams.
-
-   --    Names of the form Ada_Strings_xxx are second level children
-   --    of Ada.Strings.
-
-   --    Names of the form Ada_Text_IO_xxx are second level children of
-   --    Ada.Text_IO.
-
-   --    Names of the form Ada_Wide_Text_IO_xxx are second level children of
-   --    Ada.Wide_Text_IO.
-
-   --    Names of the form Ada_Wide_Wide_Text_IO_xxx are second level children
-   --    of Ada.Wide_Wide_Text_IO.
-
-   --    Names of the form Interfaces_xxx are first level children of
-   --    Interfaces. For example, the name Interfaces_Packed_Decimal refers to
-   --    package Interfaces.Packed_Decimal.
-
-   --    Names of the form System_xxx are first level children of System, whose
-   --    name is System.xxx. For example, the name System_Str_Concat refers to
-   --    package System.Str_Concat.
-
-   --    Names of the form System_Storage_Pools_xxx are second level children
-   --    of the package System.Storage_Pools.
-
-   --    Names of the form System_Strings_xxx are second level children of the
-   --    package System.Strings.
-
-   --    Names of the form System_Tasking_xxx are second level children of the
-   --    package System.Tasking. For example, System_Tasking_Stages refers to
