Log:
  Apply vendor revision 470df104c6f55f6d6f390df7448d8eb65c7642b9:
  
  From: Guy Harris <guy@alum.mit.edu>
  Subject: [PATCH] Fix compilation if INET6 isn't defined.
  
  Addresses GitHub issue #541, but differently from the pull request (it
  defines gen_gateway() with a function prototype rather than using a
  pre-prototype-style definition).
