--  This unit provides entities to be used internally by the units common to

--  underlying Low Level support.

--  The set of "services" includes:

--

--  o Imports to the low level routines for which a direct binding is

--    mandatory (or just possible when analyzed as such).

--

--  o Conversion routines (unchecked) between low level types, or between

--    various pointer representations.
