Summary:                    ipsec-tools doesn't compile with uclibc
Description: 
ipsec-tools (I've tried with several versions, 0.3, 0.4, 0.5rc1) doesn't
compile; in fact the configure script dies complaining about a buggy
getaddrinfo implementation.

I think the problem may be something to do with these lines from
getaddrinfo.c:

    573         struct gaih_addrtuple *atr;
    574         atr = at = alloca (sizeof (struct gaih_addrtuple));
    575         memset (at, '\0', sizeof (struct gaih_addrtuple));
    576 
    577         if (req->ai_family == 0)
    578         {
    579             at->next = alloca (sizeof (struct gaih_addrtuple));
    580             memset (at->next, '\0', sizeof (struct
gaih_addrtuple));
    581         }
    582 
    583 #if __UCLIBC_HAS_IPV6__
    584         if (req->ai_family == 0 || req->ai_family == AF_INET6)
    585         {
    586             extern const struct in6_addr __in6addr_loopback;
    587             at->family = AF_INET6;
    588             if ((req->ai_flags & AI_PASSIVE) == 0)
    589                 memcpy (at->addr, &__in6addr_loopback, sizeof
(struct in6_addr));
    590             atr = at->next;
    591         }
    592 #endif
    593 
    594         if (req->ai_family == 0 || req->ai_family == AF_INET)
    595         {
    596             atr->family = AF_INET;
    597             if ((req->ai_flags & AI_PASSIVE) == 0)
    598                 *(uint32_t *) atr->addr = htonl
(INADDR_LOOPBACK);
    599         }
    600     }


Specifically, I'm not sure what these lines are doing:

    577         if (req->ai_family == 0)
    578         {
    579             at->next = alloca (sizeof (struct gaih_addrtuple));
    580             memset (at->next, '\0', sizeof (struct
gaih_addrtuple));
    581         }

If I comment them out and build uclibc, then ipsec-tools compiles without
complaining.

I compiled ipsec-tools 0.6.7 on latest uclibc SVN/ARM arch it built ok. So
i am closing this defect as fixed.
