Ulrich Drepper 67994d6f60 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.
