This fixes the segfault i had,
when tried to connect bearbox on X86_64SMP and DNS SERVERS IPV6 compatible.
gethostbyname2() works like gethostbyname(), but permits to specify the address family (AF_INET) to which the address must belong.
Glibc2 also has reentrant versions gethostbyname_r() and gethostbyname2_r().
