This is a familiar error seen before in socket handling

I have a RaspberryPi 2 that has the armv7 processor and I'm trying to compile 0.30 version of the qpid/cpp code and having an issue with casting:

Previous versions of this error have been fixed with one new '(void*)' per line with no ill side effects.
