Two things still on my to-do list are to make sure the hash table eq
code is working correctly (I didn't update this and learned later that I
should); and that comparisons against NaN work properly (the GMP docs
say this is undefined, so we will need a special case).

I'm not sure what the semantics of NaN comparison are in Emacs.  In
particular, this doesn't really make sense to me:

    (> 0 0.0e+NaN) => nil
    (< 0 0.0e+NaN) => nil
    (min 0 0.0e+NaN) => 0.0e+NaN
    (min 0.0e+NaN 0) => 0.0e+NaN
    (max 0 0.0e+NaN) => 0.0e+NaN
    (max 0.0e+NaN 0) => 0.0e+NaN
