[BZ #18]

Update.
	* nscd/nscd_conf.c (nscd_parse_file): Little optimization.

2004-02-14  Thorsten Kukuk  <kukuk@suse.de>

	* nscd/dbg_log.c (set_logfile): Only save name of logfile,
	don't open it.
	(init_logfile): New function, open logfile if requested.
	* nscd/dbg_log.h: Adjust protoype for set_logfile, add init_logfile.
	* nscd/nscd.c (main): Call init_logfile after forking in background.
	* nscd/nscd_conf.c (nscd_parse_file): Adjust for new set_logfile.
