	* debug/catchsegv.sh: Also produce output if cloned process died.

1998-09-24  Paul Eggert  <eggert@twinsun.com>

	* strftime.c (f_wkday): Remove duplicate definition.
	(f_wkday, f_month, a_wkday, a_month, ampm): Define as macros when
	!defined _NL_CURRENT && !HAVE_STRFTIME; this propagates the
	1998-09-11 fix to this case.
	(wkday_len, month_len): Remove these macros; they're no longer needed.

1998-09-24  Paul Eggert  <eggert@twinsun.com>

	* strftime.c (my_strftime): Don't store past the end of a
	zero-sized buffer.

	* time/strftime.c (underlying_strftime):
	* time/strftime.c (INT_STRLEN_BOUND): Fix typo by changing 100 to 1000.

zero-sized buffer.
1998-09-24 Paul Eggert <eggert@twinsun.com>
* time/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.
