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.
