    Adjust test limit for 'long double' Perls. I believe that the
    problem is that the reference data were generated by a Fortran
    program using double precision rather than long double, so we're
    really dealing with a difference in rounding/truncation error. This
    really only affects Mercury, the problem child of the Solar System.
    Thanks to Slaven Rezić (SREZIC) for testing this configuration and
    exposing the issue.
