12333	boost/algorithm/hex.hpp: warning C4244: 'return': conversion from 'unsigned int' to 'unsigned char'	pravic <ehysta@…>	Marshall Clow	"… which is not surprise:


{{{

    unsigned char hex_char_to_int ( T val ) {
        char c = static_cast<char> ( val );
        unsigned retval = 0; // <--
        // ...
        return retval; // <--
        }
