Update.
1999-11-10  Andreas Jaeger  <aj@suse.de>

	* string/strsignal.c (strsignal): Correct check for snprintf
	return value.
	* argp/argp-fmtstream.c (__argp_fmtstream_printf): Likewise.

	* misc/efgcvt_r.c (APPEND): Correct check for too small buffer
	according to changed snprintf return value.
	Reported by Lawrence K. Chen <lchen@opentext.com>.

	* misc/tst-efgcvt.c (special): Add tests for a too small buffer
	for ecvt_r and fcvt_r.
