I think I'd feel more comfortable if the people who actually had the
expertise were contributing the macro.  As things stand, it sounds a
bit too indirect: I don't have a good feeling that people will
actually use the macro (regardless of whether it's in gnulib or
autoconf).  The whole area of <arpa/*> and <netinet/*> etc. is a
fairly large one, one that Autoconf hasn't ever specifically
addressed; I'm not sure it's wise to tackle just one little corner of
it without considering the big picture.

But that's also true for Autoconf.  :-)

I don't know if it's a worthwhile addition.  I'm not really an expert
in the area.

Sorry, I don't know for sure.
