This message talks about the unportability of a field 's6_addr32' in
'struct in6_addr'. Sure this is unportable: POSIX [1] specifies only the
presence of 's6_addr'.

I don't see why gnulib should support this: An application can perfectly
access the 16 bytes of the s6_addr[] array. Why would it need to access a
specific part of it in a special way?
