[BUG] autoupdate vs aclocal m4_include

[Gary V. Vaughan]

This is Autoconf-2.59, Automake-1.9.2, CVS Libtool branch-2-0:

Unless AC_CONFIG_MACRODIR is called aclocal or m4sugar, autoupdate
complains about `unknown set' if aclocal.m4 uses m4_include.  The
run still works, but there are several pages of spurious warnings.
Here's a minimal repeat recipe:

$ cat > configure.ac << '__EOF'
AC_INIT(x,0)
AC_CONFIG_MACRO_DIR(m4)
AC_PROG_LIBTOOL
AC_OUTPUT
__EOF
$ libtoolize
ibtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'.
libtoolize: copying file `m4/libtool.m4'

libtoolize: copying file `m4/ltversion.m4'
$ aclocal -I m4
$ grep m4_include aclocal.m4
m4_include([m4/libtool.m4])
m4_include([m4/ltoptions.m4])
m4_include([m4/ltsugar.m4])
m4_include([m4/ltversion.m4])

And yet by changing the directory name for AC_CONFIG_MACRO_DIR:
