So it seems that libnetutil/netutil.c:sysroutes_dnet_find_interfaces() was
never correct, I got confused by it...

I've attached a new patch 'patch -p1' for Nmap-6.01, now Nmap should detect
ppp connections, still I'm not conviced since I assume there are other
special setups which perhaps we can't handle...

Tom thanks for your patience.
