Re: ipv6 build error?

Hi Bruce,

I seem to have this:

struct in6_addr {
        union {
                u_int8_t   __u6_addr8[16];
                u_int16_t  __u6_addr16[8];
                u_int32_t  __u6_addr32[4];
        } __u6_addr;                    /* 128-bit IP6 address */
};

#define s6_addr   __u6_addr.__u6_addr8
#ifdef _KERNEL  /*XXX nonstandard*/
#define s6_addr8  __u6_addr.__u6_addr8
#define s6_addr16 __u6_addr.__u6_addr16
#define s6_addr32 __u6_addr.__u6_addr32
#endif

#define INET6_ADDRSTRLEN        46

I've attached the full header file.

ifconfig shows IPv6 addresses on the network interfaces, so I assume I have
ipv6 built.  It is a 4.4-stable box with GENERIC kernel.  I just rebuilt
from very latest CVS and it still failed.
