2nd round of Problems using date-time library

From: Keno (keno_at_[hidden])

Ok Jeff, I hope you can help with this one. Created a date object and did a
call to cout with to_simple_string(0) and got linker errors. Program and
error are below. I looked at the greg_month.hpp file and realised that the
methods complained about are declared but not implemented. Could this be the
source of the problem?

________ CODE & COMPILE ERRORS _____________

void main()
{
  using namespace boost::gregorian;

  date new_years_day(2002,Jan,10);
  std::cout << to_simple_string(new_years_day) << std::endl;
}
