Hmm. This is clisp 2.47 and cmucl (cvs) on Mac OS X. rtest_gamma, test
273 fails on both with an error of 2.476b-30 instead of the expected
1b-30. There are other failures like this where the expected accuracy
is not achieved. Then there are a few failures in rtest_expintegral
where expintegral_e continued fractions failed.
I don't understand what's going on. Since bfloat arithmetic ought to be
the same everywhere, I don't understand why you pass but I do not. More
investigation needed....
