[krbdev.mit.edu #2598] Cannot compile KRB5 on HP-UX 11

[DEEngert@anl.gov via RT]

Ken, Looking at the HP 11.11 header net/ip6.h I see that HP does support the
SIOCGLIFCONF but it uses a differnet structure then Solaris. Many of the 
comments are the same, indicating they had some common source. 

I don't quite understand the foreachaddr.c and since we do not have any
HPs with IPV6, the simplist thing was to ifdef them out for now. 
  
I have copied 3 of the header files from an HP 11.11 which pertain to 
IPv6 into AFS at /afs/anl.gov/usr/ctd/b17783/pub/hp.11.11 
If you can not access these I can send you a copy. 

If you need to test any thing, I can try and compile any changes. 
See below too.

The structure is called if_laddrconf in net/if6.h

Yes.

No, can't find libconf.
