A quick note about this one. Andi Barth has started to debug that, and
I have continued a bit. The following code doesn't work correctly on
ppc64el, printing twice a positive value.

#include <boost/math/special_functions.hpp>
#include <iostream>

int main(int argc, char **argv)
{
  const long double a = 12.34;
  std::cout << a << std::endl;

  const long double b = (boost::math::changesign)(a); 
  std::cout << b << std::endl;
}

I probably won't have time to look at that before the week-end, so don't
hesitate to have a look if you have time.
