That's why BOOST_WINDOWS was created. Just #include boost/config.h and
it'll be available to you.

boost/config.hpp:
#include <boost/config/select_platform_config.hpp>                           
#ifdef BOOST_PLATFORM_CONFIG
#  include BOOST_PLATFORM_CONFIG
#endif

boost/config/select_platform_config.hpp:
#elif defined(_WIN32) || defined(__WIN32__) || defined(WIN32)
// win32:
#  define BOOST_PLATFORM_CONFIG "boost/config/platform/win32.hpp"

boost/config/platform/win32.hpp:
#define BOOST_WINDOWS 1
