you might as well unconditionally include sys/socket.h and let it's
internal #ifndef take care of that problem.

I'm not sure why you don't just make your own new header file for
this struct unless you're adding to an existing structure in
socket.h, even if you are you can put whatever it is that you added
to netinet/in.h into a seperate header or sys/socket.h itself.
