-- Obviously the body below is incorrect, since it is simply a checked
-- conversion. Indeed it is not possible to write a correct body for
-- this generic function in Ada. The approach we take is to provide this
-- bogus body, which is read in as a generic template using the normal
-- mechanisms, then there is a special circuit (in Sem_Ch11) which checks
-- for unchecked conversion and sets the Unchecked_Conversion flag in the
-- N_Conversion node in the template.
