    double d = boost::lexical_cast<double>(""123.4"");;

boost 1.59.0 has the following warning when compile on Visual studio 2005 platform under Unicode.


1>c:\boost-v1.59.0\include\boost-1_59\boost\lexical_cast\detail\converter_lexical_streams.hpp(587) : warning C4244: 'argument' : conversion from '__w64 int' to 'boost::detail::basic_pointerbuf<charT,BufferT>::streamsize', possible loss of data

Fix: Change line 586@ boost\lexical_cast\detail\converter_lexical_streams.hpp

From: buf.setbuf(const_cast<CharT*>(start), finish - start);
To: buf.setbuf(const_cast<CharT*>(start), static_cast<std::streamsize>(finish - start));

Please review. Thanks
