I'm using gcc under Cygwin and gcc with Mingw and am getting the
following warning:

 476.       function D_Datum is new Unchecked_Conversion(Datum_Type,
AIL_List.Datum_Type);
            |
      >>> warning: types for unchecked conversion have different sizes
      >>> warning: size of "DATUM_TYPE" is 32, size of "DATUM_TYPE" is
31
      >>> warning: 1 trailing bits of source will be ignored

I understand what the message means but what is the operational
effect? What does 'ignored' mean in this context?
