+
+ * doc/autoconf.texi (Special Shell Variables): Mention POSIX
+ 1003.1-2001's requirements for CDPATH. Give a simpler workaround
+ for the CDPATH problem. Document PWD.
+ (Limitations of Builtins): Document the problem that "cd $foo" and
+ "ls $foo" may refer to different directories in shells conforming
+ to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
+ example, since the old example is now out of date.
+
+ * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
+ FOO" and "ls FOO" talk about different directories; this catches
+ problems when POSIX 1003.1-2001 "cd" fails due to symlink
+ spaghetti.
+
+ * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
+ of rolling our own unset.
+ (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
+ in practice we needn't worry about CDPATH if unset doesn't work.
+
+ * Makefile.in, aclocal.m4, bin/Makefile.in,
+ config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
+ lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
+ lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
+ lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
+ tests/Makefile.in: Regenerate with Automake 1.6.3.
+
+ * config/config.guess, config/config.sub, config/mkinstalldirs:
+ Update.
+
+ * configure: Regenerate with self.
