libtool-branch-2-0 libtoolize weirdness

[Bob Friesenhahn]

With no m4 subdirectory existing and with

  AC_CONFIG_MACRO_DIR([m4])

in configure.ac I see this odd behavior from

  libtoolize --copy --ltdl ltdl/libltdl

[ stuff removed ]
libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'.
libtoolize: `m4/libtool.m4' is already up to date.
libtoolize: `m4/ltdl.m4' is already up to date.
libtoolize: `m4/argz.m4' is already up to date.
libtoolize: `m4/ltoptions.m4' is already up to date.
libtoolize: `m4/ltsugar.m4' is already up to date.
libtoolize: warning: no serial number on 
`/usr/local/share/libtool-1.9g/m4/ltversion.m4', not copying.
libtoolize: `./ltmain.sh' is already up to date.
libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'.
libtoolize: copying file `m4/libtool.m4'
libtoolize: copying file `m4/ltdl.m4'
libtoolize: copying file `m4/argz.m4'
libtoolize: copying file `m4/ltoptions.m4'
libtoolize: copying file `m4/ltsugar.m4'
libtoolize: copying file `m4/ltversion.m4'

Notice the message about non-existent files already being up to date.
The end result seems ok, but the status messages are wrong.

Another oddity I noticed is that with

  AC_CONFIG_MACRO_DIR([.])

libtoolize reports that it is copying files to the 'm4' subdirectory 
when it is actually (properly) copying to the current directory.
