I looked at the kcalc source, and the whole thing is so broken
that you are better off just turning off HAVE_L_FUNCS regardless
of anything. KCalc casts the input and output of each libm
function it calls to double precision even if it's calling the
long double version. This means that it actually achieves *worse*
accuracy by using the long double functions, due to rounding twice.
