Hello,

""program_options"" build fail. ""boost::lambda"" is working without any problem. 

This example below doesn't work:

{{{
#include ""boost/program_options.hpp""
namespace po = boost::program_options;

#include <iostream>
#include <iterator>
using namespace std;

int main(int ac, char* av[])
{
    try {

        po::options_description desc(""Allowed options"");
        desc.add_options()
                (""help"", ""produce help message"")
                (""compression"", po::value<double>(), ""set compression level"");

        po::variables_map vm;
        po::store(po::parse_command_line(ac, av, desc), vm);
        po::notify(vm);

        if (vm.count(""help"")) {
            cout << desc << ""\n"";
            return 0;
        }

        if (vm.count(""compression"")) {
            cout << ""Compression level was set to ""
                 << vm[""compression""].as<double>() << "".\n"";
        } else {
            cout << ""Compression level was not set.\n"";
        }
    }
    catch(exception& e) {
        cerr << ""error: "" << e.what() << ""\n"";
        return 1;
    }
    catch(...) {
        cerr << ""Exception of unknown type!\n"";
    }

    return 0;
}
}}}

This example below is working:
{{{
#include <boost/lambda/lambda.hpp>
#include <iostream>
#include <iterator>
#include <algorithm>

int main()
{
    using namespace boost::lambda;
    typedef std::istream_iterator<int> in;

    std::for_each(
            in(std::cin), in(), std::cout << (_1 * 3) << "" "" );
}
}}}
