Thanks for catching that. I looked into it a bit more, and discovered
that not only do we not need to build inet_ntop on Solaris 8, we don't
even need the system's inet_ntop, nor do we need to link with -lnsl.
This stuff was included only as a dependency to getaddrinfo, but that
function isn't needed or built on Solaris 8.
I worked around the problem in the following different, and I hope
simpler way, though it is a bit hacky. This time I remembered to push
it, anyway....
-----
* modules/arpa_inet (arpa/inet.h): Depend on arpa_inet.in.h.
* m4/inet_ntop.m4 (gl_INET_NTOP): Search for inet_ntop in -lnsl,
for Solaris 8. This is a bit of a hack, as it means it's the
caller's responsibility to add -lnsl if needed, but most likely it
won't be needed since only getaddrinfo uses this and getaddrinfo
isn't needed on Solaris 8.
