--- Comment #1 from Bruno Haible <bruno at clisp dot org> ---
It works when I declare ys1, ys2, zs1, zs2 as 'volatile double' instead of
'double'. But I should not be needing to do this, because the only uses of
these 4 variables is as arguments to equalfn, which takes 'volatile double *'
arguments, which ought to already do the truncation from extended-double format
to double format.
