Thank you, John! That'd definitely help a lot.
Oh, and while you're at it, it'd be interesting to also try the offending snippet that Marc originally provided:
http://lists.boost.org/boost-users/2006/12/24313.php
with the corrections I suggested at
All the tests pass. The code that was posted doesn't compile for me, I see: Compiling... scrap.cpp c:\data\boost\1.33.1\boost_1_33_1\boost\multi_index\composite_key.hpp(154) : error C2039: 'result_type' : is not a member

So I gave up at that point. Adding your example programs to the same VC7.1 IDE project did compile so I don't think it's a setup issue. John.
