Can the pair be declared without a typedef? Is this a limitation of the MS compiler?

It is a limitation of the preprocessor. It does not recognize <> as any sort of parentheses, so it thinks the , separating the template parameters is a macro argument separator. You can try wrapping the whole argument in parentheses: BOOST_FOREACH((std::pair p), m) But I'm not sure if the PP passes the parentheses on - in that case, you might get syntax errors in the generated code. If that's the case, you'll have to use the typedef.
