Yes, that's right.

When I wrote that (a few years ago) the Dev versions of Libtool, Automake and
Autoconf collaborated on support for multiple macro directories. It won't work
out of the box until all of the pieces are in released versions, though we're 
only
waiting on Autoconf now that Libtool has finally revved.

The release notes also show a workaround if you  want to use (plural!)
AC_CONFIG_MACRO_DIRS now, without depending on an unreleased Autoconf
build to bootstrap.

Or, in the common case, you may only need a single macro directory anyway,
in which case (singular) AC_CONFIG_MACRO_DIR continues to work just fine :-)

Cheers,
