Update.
1999-06-23 Ulrich Drepper <drepper@cygnus.com>
* manual/arith.texi: Document restriction of ndigit parameter of
ecvt and friends.
* misc/efgcvt.c: Define NDIGIT_MAX.
(gcvt): Limit precision in sprintf call to NDIGIT_MAX.
Do not dynamically allocate the static buffers. They are small enough.
* misc/efgcvt_r.c: Define NDIGIT_MAX.
(fcvt_r): Limit precision in snprintf call to NDIGIT_MAX.
* misc/qefgcvt.c: Define NDIGIT_MAX.
* misc/qefgcvt_r.c: Likewise.
* misc/tst-efgcvt.c (special): Add test for large ndigit parameter.
