Hello, Running Boost 1.44, VS2008 SP1, W SDK 6.1, W Server 2003 When I compile; #include <boost/date_time.hpp> I get the following compiler warnings; ... c:\program files\microsoft visual studio 9.0\vc\include\iosfwd(589) : warning C4996: 'std::_Traits_helper::copy_s': ... ... c:\program files\microsoft visual studio 9.0\vc\include\iosfwd(616) : warning C4996: 'std::_Traits_helper::move_s': ... ... c:\program files\microsoft visual studio 9.0\vc\include\iosfwd(607) : warning C4996: 'std::char_traits<char>::copy': ... ... etc.. Above is caused by resent changes to tokenizer, more specific token_functions.hpp for ticket 1755, starting with revision 62706. When I revert token_functions.hpp to version of 1.43 warnings go away. When I compile (copied from boost/date_time/date_parsing.hpp); #include <boost/tokenizer.hpp> typedef std::basic_string<char>::traits_type traits_type; typedef boost::char_separator<char, traits_type> char_separator_type; void foo() { const char sep_char[] = {',','-','.',' ','/','\0'}; char_separator_type sep(sep_char); } I get identical warnings; Kind regards, Okko Willeboordse
