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 
that.

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,
Norbert
