 The function rint is not present in the libraries of Visual Studio 2008.

 I propose, that line 28 in msvc_rounding_control.hpp

 extern "C" { double rint(double); }

 is replaced with John Maddock's workaround from the boost-users mailing
 list:

 #if BOOST_MSVC < 1400
 extern "C" { double rint(double); }
 #else
 inline double rint(double x)
 {
 _asm FLD [x] ;
 _asm FRNDINT ;
 //_asm RET ;
 }
 #endif

 since certain constructs simply do not link right now (the linker
 complains that the function rint is missing).
