	* src/extract.c (ARCHIVED_PERMSTATS): Add a comment saying that
	S_IRWXG | S_IRWXO might be masked out.
	(set_mode): Set the mode if some bits were masked out originally.
	(set_stat): Don't chmod before chown, as that might temporarily
	grant permissions that we don't want to grant.  The chmod was
	there only to work around broken hosts, so add a comment advising
	users not to use those broken hosts instead.
	(repair_delayed_set_stat, extract_dir):
	Remember to mask out current umask before inverting permissions.
	(extract_dir): If the owner might change, or if the mode has
	special bits, create the directory 700 at first, but restore it later.

	(extract_file, extract_node, extract_fifo): If the owner might
	change, omit group and other bits at first, but restore them after
	changing the owner.

	Port to latest gnulib.  There were a lot of changes, so the

	does this.

	* lib/Makefile.tmpl: Remove, replacing with....
	* lib/Makefile.am: New file.
