I can't compile this simple application from CVS HEAD using g++ (3.3.6 and 4.1.1). Not sure if this is date_time, range, or string_algo at fault here or perhaps something else: #include <boost/date_time/posix_time/posix_time.hpp> #include <iostream> using namespace std; using namespace boost::posix_time; int main () { ptime now = microsec_clock::local_time(); cout << now << endl; } I get these errors: /home/cepstein/src/boost/boost/range/const_iterator.hpp: In instantiation of `boost::range_const_iterator<const char*>': /home/cepstein/src/boost/boost/algorithm/string/replace.hpp:654: instantiated from `void boost::algorithm::replace_all(SequenceT&, const Range1T&, const Range2T&) [with SequenceT = std::basic_string<char, std::char_traits<char>, std::allocator<char>
