The attached is the set of new or modified files with approach 1.  The
difference is quite big, so I didn't make "patches".  A tiny version
of getaddrinfo() is included, which was derived from the
implementation of the KAME project.

I've tested the new kit from configure on SunOS 5.6 (as an example
that does not have getaddrinfo()), and confirmed that it works well
for IPv4.
