OK, so here you get an average error of roughly 1.21, and the
precision test requires it to be no bigger than 1.2, so it fails.
Of course this 1.2 value comes from past experiment, so now that we
see a case where it should be increased, let's increase it. Can you
set it to 1.3 and add a comment that it used to be 1.2 and you raised
it because gcc 4.1 was giving 1.21.
