Log message:
        * 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        example, since the old example is now out of date.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.
