Ulrich Drepper 34c86f4254 Update.
2003-02-08  Ulrich Drepper  <drepper@redhat.com>

	* io/ftwtest.c: Get current working directory before and after the
	nftw call and make sure they match.

2003-02-08  Jim Meyering  <jim@meyering.net>

	* ftw.c (ftw_startup): When using FTW_CHDIR, always remember
	the current directory, not just when DIR contains a slash.
	Reported by Manoj Srivastava.
