    qd-gamma.lisp:
    o For integer values, just compute the gamma value directly by
      multiplication.  This works around the problem that the current
      algorithm is not as accurate as we would like.
    
    rt-test.lisp:
    o Reduce required accuracy in gamma-incomplete-tail.3.d.
    o Add precision test for gamm incomplete tail near the negative real
      axis.
