 First, Boost.DateTime no longer includes windows.h by default. You can
 explicitly enable it to include windows.h by defining BOOST_USE_WINDOWS_H.

 Second, defining WIN32_LEAN_AND_MEAN will disable quite a few components
 in windows.h. Boost.DateTime is in no position to enforce this decision in
 its headers. If you want windows.h to behave like when WIN32_LEAN_AND_MEAN
 is defined, you should define it in your project, before including any
