[Boost-users] WIN32_LEAN_AND_MEAN

My projects need to define WIN32_LEAN_AND_MEAN.  Unfortunately, they receive 
many compilation warnings due to macro redefinition in the following Boost 
headers (1.34.1).

boost/iostreams/detail/system_failure.hpp
boost/spirit/iterator/impl/file_iterator.ipp

I understand that I can avoid the need to define WIN32_LEAN_AND_MEAN by 
ensuring that Boost headers are always included prior to <windows.h>.  I do 
not like the idea of include order dependencies, as I am certain that I will 
come back to bite me down the road.

Another option would be to turn the particular warning off; however, I would 
rather not do this.

Would it be prudent to patch the Boost headers to only define 
WIN32_LEAN_AND_MEAN if it is not already defined?  If not, is there another 
solution that I am overlooking.

Thanks,
Justin
