1.30.0, as you said, doesn't has the using declaration at function scope, BUT is has it at namespace scope. See revision 1.9 or prior. The idea was that borken GCC don't like it at function scope but do at namespace scope. Recently, Jens Maurer changed the guard at function scope from: #ifndef __GNUC__ to #ifndef BOOST_NO_STDC_NAMESPACE and honestly, I didn't looked much at it as I should. BOOST_NO_STDC_NAMESPACE is documented to relate to C names, but swap is a C++ name so I don't think such macro should be used here. I don't understand the problem with the original code (as of revision 1.19), and I don't understand why 1.30.0 fails. I do understand why HEAD fails, by my 'fix' would be to revert Jens fix, but if I were right, 1.30.0 wouldn't fail as it does.
