Surely the definitions 0^0 = 1 and 0.0^0 = 1.0 are consistent (law
of exponents), no? That Axiom treats 0^(0.0) as undefined also seems
consistent to me since a floating point 0 is not identical to the
integer 0. But there is a problem with the error message
"protected-symbol-warn called with (NIL)".
