By the way: In GCL (expt 10.0d0 6.0d0) --> 1000000.0000000013, but both CCL and Allegro give
1000000.0. For GCL, the relative difference between the true and floating point value is
about 10 times the machine epsilon. I don't know what the IEEE standard says about the
accuracy of floating point exponentiation, but ten times the machine epsilon seems too big.
