5519	Error C4235 in msvc_rounding_control.hpp (numeric.interval_lib.detail)	hajokirchhoff	Jürgen Hunold	"The code tests WIN64 when it should test _WIN64.

WIN64 is not a Microsoft standard preprocessor macro. _WIN64 is correct (see Microsoft documentation http://msdn.microsoft.com/en-us/library/b0084kay%28VS.80%29.aspx)

The effect is that the inline _asm function gets compiled when using the 64 Bit MSVC Compiler, which results in a C4235 error (_asm is not supported).

Fix: Use _WIN64 instead of WIN64 to test for 64 Bit MSVC
{{{
#if BOOST_MSVC < 1400 || defined(WIN64)

#else
inline double rint(double x)
{
_asm FLD [x] ;
_asm FRNDINT ;
//_asm RET ;
}
#endif
