Boost 1.38, Vis Studio 2005, and the issue is that unless I put the main
Boost.Asio header first in my #include list I get a failure message

WinSock.h has already been included

from socket_types.hpp.

The workaround for this is to #define WIN32_LEAN_AND_MEAN before including the windows header. The problem is really that windows.h includes so much stuff in it.

It looks like Boost.Asio defines WIN32_LEAN_AND_MEAN by default anyway (http://www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/using.html).

Cheers,
Darren
