Not quite. I didn't think of that possibility, since I usually don't
import anything into the global namespace. But I found an (unnecessary)
include of <boost/signal.hpp>. And that was enough to cause the problem.

So thank you very much for the quick solution. I totally didn't think of

I now managed to build a testcase that consists of an empty main()
function and the two includes, that causes the described error. See the
code below.

thanks for your hint,

#include <boost/signals.hpp>
#include <boost/asio.hpp>

int main(int argc, char **argv)
        return 0;
