Adds --with-lwres and --enable-emulate-getaddrinfo but are not used in any of
the code at this time. Has a check for IPv6 support but only runs if using the emulate-getaddrinfo routines, this needs to be modified. !!! I need input from results of this run on various platforms to see what results are seen in plugins/config.h so please help test !!! git-svn-id: https://nagiosplug.svn.sourceforge.net/svnroot/nagiosplug/nagiosplug/trunk@371 f882894a-f735-0410-b71e-b25c423dba1c
