From f9db9985e1a0a2da0f21fc3dbfd92bf12f924d1e Mon Sep 17 00:00:00 2001 From: Matthias Andree Date: Mon, 15 May 2006 10:59:45 +0000 Subject: * Improve KAME/getnameinfo.c portability to Linux libc5 systems. Based on a patch by Dan Fandrich. * Provide INET6 to KAME/getnameinfo.c (only useful on IPv6-enabled systems that lack getnameinfo, and there only visible in some Received: headers).
