No, the #if can't be removed completely, that's the build failure that 
Ronald pointed out as a problem in my first attempt to remove the ipv4 
codepath in udp.c. It needs some check, at least for struct sockaddr_in6. 
I'll be back with another attempt at this, soon.

Ok, I'll finish that one then.
