It was only added in the first place because the IPv6 API drafts required it.
The newer versions of these specifications have dropped the requirement so I 
pulled it from libc again.  It was never a good idea to have <sys/socket.h> 
pull in all the address-family-specific code, and there were a few corner 
cases where you could trick it into multiply defining things or not defining 
them at all by including things in the right order.  To be honest I didn't 
expect anybody to be using sockaddr_union; sorry.

I think the later API specifications do include something with similar 
intent (a block of memory large enough to store any sockaddr structure) but 
this isn't implemented yet.  If you'd like to have a crack feel free to send 
me a patch.
