+ * sysdeps/unix/sysv/linux/bits/in.h
+ [_UAPI_LINUX_IN6_H]: Define __USE_KERNEL_IPV6_DEFS.
+ * inet/netinet/in.h: Move in_addr definition and bits/in.h inclusion

+ * inet/netinet/in.h [!__USE_KERNEL_IPV6_DEFS]: Define IPPROTO_MH, and

+ [__USE_KERNEL_IPV6_DEFS]: Don't define any of IPPROTO_*, in6_addr,
+ sockaddr_in6, or ipv6_mreq.
