Thanks for the replies. You are right, I did a rebuild of boost passing now the architecture=x86 parameter (I think that I left it out the first time - I think that I saw somewhere that this has to be explicitly specified) and the code generated is definitely 64-bit (although it still shows "32-bit: yes" during the build).

Thanks again,

I've seen this with earlier Boost releases as well with VS2013; I don't
think it's a Boost 1.60 issue specifically.
