^^
I would assume the marked code is for IPV6 so needs to be protected by=20
ENABLE_IPV6, for example:
#ifdef ENABLE_IPV6
char packed[MAX(sizeof(struct in_addr), sizeof(struct in6_addr))];
#else
char packed[sizeof(struct in_addr)];
#endif

(I do not use the Python build system as I have to cross-compile and so u=

Sorry, it was a question. See above.

Thanks. The RTEMS TCP/IP stack is an old port of the FreeBSD stack and do=
es not=20
have this. The current FreeBSD does so I will fix RTEMS. I will not add=20
INET6_ADDRSTRLEN as no other IPV6 support is currently provided.
