Update.

1998-01-31 20:52  Ulrich Drepper  <drepper@cygnus.com>

	* nscd/grpcache.c (cache_grpinit): Let calloc do the multiplication.

	* nscd/pwdcache.c (cache_pwdinit): Use thread attribute to detach
	thread and no pthread_detach.

	* nscd/nscd.c: Rewrite to use argp instead of getopt.

	* config.make.in: Likewise.
