Hi: When using the string algo library func tion is_any_of, I get the following warning under visual c++: c:\program files\boost\boost_trunk\boost/algorithm/string/detail/classification.hpp (102) : warning C4996: 'std::copy': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators' Could secure warnings be turned off, or could we potentially look int o using checked iterators with visual c++? Also, I get the following isues: c:\program files\boost\boost_trunk\boost/algorithm/string/classification.hpp(206) : see reference to function template instantiation 'boost::algorithm::detail::is_any_ofF::is_any_ofF>(const RangeT &)' being compiled with [ CharT=char, IteratorT=const char *, RangeT=boost::iterator_range ] Is this something I should worry about, what does this mean? Any help apreciated.
