	* strftime.c (underlying_strftime):
	Set the buffer to a nonzero value before calling
	strftime, and check to see whether strftime has set the buffer to zero.
	This lets us distinguish between an empty buffer and an error.

	* strftime.c (INT_STRLEN_BOUND): Fix typo by changing 100 to 1000.
	This fix is propagated from tzcode1998g.tar.gz.
