 Hi, I tried to run the Flight Time Example in
 boost_1_46_1/doc/html/date_time/examples.html#date_time.examples.simple_time_zone,
 and an exception was thrown with error message:
 terminate called after throwing an instance of
 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast>
 >'
   what():  bad lexical cast: source type value could not be interpreted as
 target
 When I debug with step into, I found it happened on line "Africa/Cairo" of
 the date_time_zonespec.csv, because this is the first timezone which needs
 to call dst_adjustment_offsets(), and there was a '\r' at the end of the
 line, then when str_from_delimited_time_duration() called
 boost::lexical_cast<unsigned short>(*beg) the '\r' made the exception
 being raised.
 On linux, std::getline(ifs, buff) in load_from_file() will leave the '\r'
 in buff, which caused the exception. On win32 this would not happen. So
 the line ends '\r' needs to be removed in load_from_file() or at the
 beginning of parse_string().
