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<int, int> 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.
