Update.

2003-02-07  Jim Meyering  <jim@meyering.net>

	* io/ftw.c: Add autoconf-recommended block of alloca-related code.
	Include autoconf-recommended block of dirent/NAMELEN-related
	definitions and includes.  Use NAMELEN throughout, rather than
	_D_EXACT_NAMLEN.
	[_LIBC]: Define NAMELEN to _D_EXACT_NAMLEN.
	[!_LIBC] (__getcwd): Define to xgetcwd and declare xgetcwd.
	(stpcpy): Declare, if necessary.
	(mempcpy): Define, if necessary.
	[!_LIBC] (__stpcpy, __mempcpy): Define.
	[!_LIBC] (LXSTAT, XSTAT): Define.
	(lstat) [!LIBC && !LSTAT_FOLLOWS_SLASHED_SYMLINK]: Define to rpl_lstat.
	(find_object): Don't use c99-style struct initializer.
	Tweak wording in a couple comments.
