+	Fix Debian bug 230872, originally reported by Jeff King in
+	<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=230872>.
+
+	* doc/tar.texi (posix compliance): Remove.  The whole section
+	was a misunderstanding of what POSIXLY_CORRECT is supposed to
+	mean.  The GNU Coding Standards says that POSIXLY_CORRECT
+	is for disabling extensions that are incompatible with POSIX:
+	it is not for disabling compatible extensions.  All references
+	to this section removed.
+	(posix): This format is created only if the posix format is
+	specified; it is no longer created if gnu format is specified
+	and POSIXLY_CORRECT is set.
+	* src/tar.c (decode_options): Ignore POSIXLY_CORRECT.
+	POSIX does not specify the behavior of tar, so we should
+	not worry about POSIXLY_CORRECT here.
