-# Written by Jim Meyering.
-# Use Gnulib's robust replacement chdir function.
-# It can handle arbitrarily long directory names, which means
-# that when it is given the name of an existing directory, it
-# never fails with ENAMETOOLONG.
-#
-# FIXME: we don't really want to use this function on systems that
-# do not define PATH_MAX...
-#
-# It still fails with ENAMETOOLONG if the specified directory
-# name contains a component that would provoke such a failure
-# all by itself (e.g. if the component is longer than PATH_MAX
-# on systems that define PATH_MAX).
