For user-defined "=" in Ada 83, the result had to be Boolean, the two
parameters had to be of the same type, that type had to be a limited
private type, and "/=" was implicitly defined.
For user-defined "=" in Ada 95, if I'm not mistaken, the result and
the parameters can be of any type. *IF* the result is Boolean, then "/="
is implicitly defined, and if not, then we may optionally redefine "/=".
