NO_YP_LIBC breaks 5.3-BETA buildworld

PS: I've posted a similiar mail to _at_stable, but not a dupe ;)

Hi!

For some time I've been wanting to use NO_YP_LIBC with buildworld for  
my jails, to enable NIS on the host system but keep the jails  
functioning.

I noticed back in August that a patch was submitted to make this work  
on then-CURRENT (I'm copying the author on this one, hoping I'm not  
acting inappropriately by doing so):
http://lists.freebsd.org/pipermail/freebsd-arch/2004-August/002550.html

Sadly, when compiling 5.3-BETA (as of 30 minutes ago), buildworld gives  
me the following errors:

...snip snip...

This feature would be very useful, and it is sad to see that it has  
once been in the tree but that it does not work any longer.

Here's to hoping someone can look into it (Bjoern, are you reading  
this? ;)

Thanks,
