[Boost-users] macro redefinition errors

Hi,

My project uses boost 1.34.1 libraries for asio and also includes
windows.h (which in turn includes winsock.h). This results in a macro
redefinition error for FD_SETSIZE and then goes on to spew a
bucketload of related errors.

The easiest way to reproduce this is to have a simple main.cpp with just:

#include<boost/asio.hpp>
#include<windows.h>
int main() { return 0; }

Any ideas on what I'm doing wrong? Or what I could try? I've tried
defining WIN32_LEAN_AND_MEAN, IPPROTO_V6 in the makefile, but to no
avail.

I'm using VC 8 on a windows XP.
========================
My comand line looks like this:
C:\perforce\some\path\>make main.o

-- Compile main.cpp...

-Ic:/perforce/toolchain/win32/winsdk-6.1.6000/VC/include
-Ic:/perforce/toolchain/win32/winsdk-6.1.6000/VC/PlatformSDK/Include

And the error message looks like:
