NO, NO, NO! The author of this doesn't seem very knowledgeable in Ada. What
you do if you need logical operators on integers is of course:

FUNCTION "XOR"( IN Number : integer) RETURN boolean_value;

And to implement this functions is not very hard, unless you don't want
go as fast as an assembler instruction.
