The source of System, Text_Io, ... is in the file src/predef.ada.
Unfortunately the text of Unchecked_Conversion is ..
generic
type SOURCE is limited private;
type TARGET is limited private;
function UNCHECKED_CONVERSION(S : SOURCE) return TARGET;
function UNCHECKED_CONVERSION(S : SOURCE) return TARGET is
NOT_USED_ANYWAY: TARGET;
begin
raise PROGRAM_ERROR;
return NOT_USED_ANYWAY;
end;
.. so I guess there's some work to do there. Obviously the body needs to
be implemented in the host language :-)
