[Bug target/30599] long double declaration rounds to double instead

It may be C99, but since it doesn't work on 90% of the machines in the world,
it is a bit of a stretch to call it portable.  My point is no standard mandates
you round down a long double (where you don't round down a double), and that
would provide a solution that *would* port to cygwin.  

So I ask again, why do you need to round down a long double, but not a double
accumulator?  Note that none of this would be necessary if gcc didn't randomly
round down doubles upon spills; remember that I switched to long double because
*you* declared it to be a solution since you did not plan to fix the original
spill/rounding bug.  I am trying to get a math library working portably despite
these problems, but it seems I'm going to be prevented by interdependent gcc
bugs that will never be fixed.
