...so this is a bug in the system headers that we're working
around? It would probably be useful to say so in a comment
in configure, otherwise it's liable to get ripped out in
future when somebody notices it's not used any more.
(For instance HAVE_IFADDRS_H isn't used and looks like dead
code in configure.)
