#serial 1
# 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).
