There is a bug in the visual studio 2010 and up compiler which causes 
real support to break. Its easiyl fixable though:

Replace line 136 in longdouble.h
template<typename T> inline longdouble ldouble(volatile T x) { 
longdouble d; d.set(x); return d; }

with
template<typename T> __declspec(noinline) longdouble ldouble(T x) { 
longdouble d; d.set(x); return d; }

And your unittests should run again.

Visual Studio 2008 and older don't have that problem.
