-- This body is provided as a work-around for a GNAT compiler bug, as GNAT
-- currently does not compile instantiations of the spec with imported ghost
-- generics for packages Signed_Conversions and Unsigned_Conversions.
-- Ghost code in this unit is meant for analysis only, not for run-time
-- checking. This is enforced by setting the assertion policy to Ignore.
