--- Comment #8 from Gianfranco <costamagnagianfranco at yahoo dot it> --- Thanks to you Markus, I spent almost one entire week in removing code in order to have something "useful" for you, and this is the maximum I could achieve. I don't know how much I can help you, your build failure is caused from the fact that you didn't rebuilt your boost framework with the new ABI?
