Update.

2004-05-07  Dmitry V. Levin  <ldv@altlinux.org>

	* argp/argp-help.c (__argp_error, __argp_failure): Check result
	of __asprintf call and don't use string if it failed.
	* stdio-common/psignal.c (psignal): Likewise.
	* locale/programs/localedef.c (more_help): Likewise.
	* resolv/res_hconf.c (arg_service_list, arg_trimdomain_list,
	arg_bool, parse_line): Check result of __asprintf calls and
	don't use string if they failed.
	* sunrpc/svc_simple.c (registerrpc, universal): Likewise.
	* elf/ldconfig.c (parse_conf_include): Check result of __asprintf
	call and exit if it failed.
