Update.
2002-05-21 Jakub Jelinek <jakub@redhat.com>
* resolv/resolv.h (struct __res_state): Remove unused nstimes.
Add nsmap.
* resolv/res_init.c (__res_vinit): Initialize nsmap array.
Remove nstimes setting.
(res_nclose): Check all MAXNS nameservers with non-NULL nsaddrs.
* resolv/res_send.c (res_nsend): Don't close unconditionally if
there is mix of IPv6 and IPv4 nameservers.
Use nsmap array to find free slots and preserve nameserver ordering.
Fix RES_ROTATE.
