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

[Dehner, Benjamin T.]

Thanks for the replies.  I've implemented Ken's work-around and defined the
ioctl's out, and it has allowed me to compile the source code.  I'm not at a
point right now where I can perform a functional test.  Also, we do not have
any IP6 in our environment that I can test against.  Apparently, others have
seen similar issues, because there is a reference to BIND9 on
http://www.isc.org/product/BIND/bind9.html that HP-UX 11.11 is not supported
due to incompatible ioctls.

Also, when I started compiling, there is also an issue in
appl/bsd/compat_recv.c.  It references a header file "sys/select.h", which
does not exist on HP.  I have 10.20, 11.0, and 11.11 systems, and none of
them had it.  By removing this file, I (apparently) could work around it.
Again, I have not performed any functional tests yet.

Thanks,
Ben

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.
