I believe you have to explicitly configure msvc, providing the path of the regular
32-bit compiler, like this:

        using msvc : 8.0 : "C:\\Program Files (x86)\\Microsoft Visual Studio 8\\VC\\BIN\\cl.exe" ;

and then, you should say:

        bjam address-model=64

or

        bjam address-model=64 architecture=opteron

I've just some fruitfull off-list discussion with Ilya Sokolov, who
explained quite some details about msvc 64-bit support, but haven't yet converted
that to docs.
