cross-compiling hurd and glibc version

[Allan McRae]

Hi,

I am trying to cross-compile a GNU system and have run into an "issue" 
compiling Hurd.  Currently, I am cross-compiling with binutils-2.19.1, 
gcc-4.1.2 and glibc-2.7 using the patches from here: 
http://www.schwinge.homeip.net/~thomas/tmp/glibc-patches/  (all 00xx- 
patches, cvs-MSG_NOSIGNAL.diff and new-needed-1.patch).

After working around bug 20151, the error I get cross-compiling hurd 
(current git) is:
...
In file included from 
../../hurd/pfinet/linux-src/include/linux/netdevice.h:133,
                from ../../hurd/pfinet/linux-src/net/ipv6/addrconf.c:33:
../../hurd/pfinet/linux-src/include/linux/skbuff.h: In function 
'__skb_pull':
../../hurd/pfinet/linux-src/include/linux/skbuff.h:497: warning: pointer

../../hurd/pfinet/linux-src/include/linux/skbuff.h: In function 'skb_pull':

'ipv6_addr_type':
../../hurd/pfinet/linux-src/net/ipv6/addrconf.c:195: error: 'struct 
in6_addr' has no member named '__in6_u'

This is "caused" by commit 30c7c06a, which updates the usage of the 
in6_addr struct to what is provided by newer glibc releases.  Is there 
another patch for glibc-2.7 to fix this or, even better, a patch-set for 
a newer glibc version?

Thanks,
Allan
