Perhaps these are bugs in 19d.  Cmucl 2010-08 gives no errors in the
testsuite.

According to the logs, this test was added in Dec 2007.  This might be
an issue with that version of cmucl.  IIRC, maxima sometimes computes
1^N for very large N.  Cmucl would warn about raising a number to a
large N.  At some point cmucl added a test so that 1^N doesn't produce
that warning, since, obviously, it's not a problem for any N.

This test is fairly new.  I'm almost positive this is an issue in 19d
where (expt 2d0 3) doesn't have full double-float precision.

Tests 100 and 109 were added in Mar 2008.  I don't know why cmucl 19d
fails these.  Is the accuracy less than expected?
