But libltdl makes use of mkstamp as well, see ltdl/configure.ac:

# This is a sanity check so we can see which version is used in bug reports.
# It is assumed that we only want to see the date extension for cvs libtool
# versions (i.e. "odd" letters) and not actual alpha releases.
TIMESTAMP=
case $lt_alpha in
  [[acegikmoqsuwy]])
    TIMESTAMP=`${CONFIG_SHELL} ${ac_aux_dir}/mkstamp < ${srcdir}/ChangeLog`
    AS_BOX([Configuring AC_PACKAGE_TARNAME (Build:$TIMESTAMP) AC_PACKAGE_VERSION])
    echo
    ;;
esac
AC_SUBST([TIMESTAMP])

Hmm, that code is broken: lt_alpha is not set, and ltdl should just ship
with mkstamp.  OTOH, I must say that I don't like this banner in libltdl
much: we haven't displayed it in a long time, other users of libltdl
have their own ways of printing banners so this would look a bit ugly
for them, and the libltdl version used is always shown in the head of
config.log.

Any reason not to apply this patch to Libtool HEAD?

Cheers,
Ralf

	* libltdl/configure.ac: Drop the broken and long-disabled code
	to output a banner for the libltdl configure.  Avoids the need
	to ship mkstamp with libltdl.
