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.
