Gained:
__weak_alias(__res_get_state, __res_get_state_nothread)
__weak_alias(__res_put_state, __res_put_state_nothread)
__weak_alias(inet_cidr_ntop,_inet_cidr_ntop)
__weak_alias(inet_cidr_pton,_inet_cidr_pton)

Lost:
__weak_alias(dn_comp,__dn_comp)
__weak_alias(dn_expand,_dn_expand)
__weak_alias(herror,_herror)
__weak_alias(res_close,__res_close)

__weak_alias(res_mkquery,_res_mkquery)
__weak_alias(res_query,_res_query)
