Update.
2001-01-03  Jakub Jelinek  <jakub@redhat.com>

	* resolv/resolv.h (struct __res_state): Add nsinit field.
	* resolv/res_send.c (res_nsend): Use it instead of nscount.
	* resolv/res_init.c (__res_vinit): Initialize it.
	(res_nclose): Clear it instead of nscount.

	* malloc/mtrace.pl: Fix matching of addresses.
	Patch by Aharon Robbins <arnold@skeeve.com>.
