 Please don't, it would be embarassing. I sent that patch 3 years ago,
 when I was only halfway through K&R. I can't believe it's taken that
 long to be looked at. I suspect no-one had the heart to close it,
 saying 'this is ugly as sin, I'm not committing this')..
 
 
 It was a kludge at the time (there *must* be a saner way to check an
 IP than to use strcmp) and it's not right to commit such a mess.
 
 A better fix would be to backport rpcbind to 4.* - I just checked that
 on a 5.3 system and it works as documented - then the portmap code could
 be taken out and shot.
 
 NB: this doesn't work for tcp ports in any case, and I don't know enough
 about NFS to know why '-h' only applies to udp. So a firewall would be a 
 safer option if you are concerned about exposing ports. But feel free to 
 use the patch if it's any use to you.
