It will help me if you can say more about exactly what is being
tested.  I see DoubleFloat computations, from what I discussed two or
three days ago, the underlying representation is Lisp' long-float --
which I think is bogus.  That representation tends to differ from
platform to platform along with the accuracy.  I believe double-float
is more portable with predictable accuracy across platforms.  Also,
there are platform-dependent libm variations to factor in (plus
C compiler optimizations).  Those remarks may or may not be relevant,
but it would help me to understand yoru issue if you could elaborate a
bit.   See below, results with build-improvements, on an
i686-suse-linux.
