I do not have any "killer" arguments for or against it, I just

Right, I allways use the BSD socket interface, so I forgot about
the other one.

Well, I didn't count them, I also saw (at least one) other that is around
a system call, but the only difference between the WIN32 and the other
version is a typecase either to socklen_t* and int* of one of the
