Parts of "libtool" are ofered under a special exception.  For example, 
in ltdl.c I see

"
As a special exception to the GNU Lesser General Public License,
if you distribute this file as part of a program or library that
is built using GNU Libtool, you may include this file under the
same distribution terms that you use for the rest of that program.
"

In fact in libtool-2.4.6 I see 51 files which mention "special 
exception".

This may be why the normal blanket statement does not appear in the 
--version text.

That would be great since post-Gord authors produced most of the 
current product.
