Thanks again Stjepan.

I think I've fixed most of the "trivial" failures (limits too tight) in SVN, 
but there are a couple of functions where I'm not sure what's going on. 
After an SVN update can you try running the program below: hopefully 
comparing the results to Linux will give me some clue what's going on, and 
whether there's anything to worry about or fix!

#define BOOST_MATH_INSTRUMENT
#include <boost/math/special_functions.hpp>

int main()
{
std::cout << std::setprecision(20);
long double d = boost::math::erfc(89.71L);
std::cout << "erfc(89.71L) = " << d << std::endl;
d = boost::math::cyl_bessel_k(0.0L, 8072.0L);
std::cout << "cyl_bessel_k(0.0L, 8072.0L) = " << d << std::endl;
return 0;
}

Many thanks, John.
