I'm building the below tiny boost app with the WDK (note that I'm
*not* building a driver or anything kernel-mode, just a regular
userland C++ app), but I'm getting the following errors when linking
with the boost libraries that I built earlier using bootstrap and
.\bjam (from the same terminal window). Anyone know what the problem
is, and how I might fix or work around it?

  boost::program_options::options_description desc("Allowed options");
  return 0;
}
