Yep, date_time is including windows.h, which includes winsock.h.

You can reverse the inclusion order to make it work. Defining
WIN32_LEAN_AND_MEAN will also prevent windows.h from including
winsock.h. The asio headers already include the following
construct to #define WIN32_LEAN_AND_MEAN:

# if !defined(BOOST_ASIO_NO_WIN32_LEAN_AND_MEAN)
#  if !defined(WIN32_LEAN_AND_MEAN)
#   define WIN32_LEAN_AND_MEAN
#  endif // !defined(WIN32_LEAN_AND_MEAN)
# endif // !defined(BOOST_ASIO_NO_WIN32_LEAN_AND_MEAN)

Perhaps something similar should be added to date_time, since
it does not need winsock.h?

Cheers,
Chris
