The popc version has been updated. It is far from perfect (lots of popc specific hacks), it lacks an IOManager parclass, but this is the minimum that we need for Alpine3D...

The ptr_to_function to ptr_to_object cast warning has been turned off (at least for gcc). This does not fix the core issue (that has to be dealt with by the future c++ standard), but at least we don't see it anymore...
