Sorry, I thought it was pretty obvious. My bad, I'll elaborate:

std::string strValue;
po::options_description desc("Allowed options");
desc.add_options()
("help,h", "Produce help message")
("string,s", po::value<std::string>(&strValue), "A string value");

works, whereas:

std::wstring strValue;
po::options_description desc("Allowed options");
desc.add_options()
("help,h", "Produce help message")
("string,s", po::value<std::wstring>(&strValue), "A string value");

doesn't even compile on MS VS 2005 (Win XP) boost version 1.34.1. It should
be very easy to test.
