        I'd classify it as a 'nuance' before calling it a bug.  :)  The
problem with rolling back to am-1.9-generated files is that the's reference 'automake-1.9' and 'aclocal-1.9' (from the
'missing' script arguments), which won't work for someone who only has
        No elegant solution comes to mind yet.  Wishful thinking would be
to have the auto-regeneration commands be smarter and attempt autotool
version detection, perhaps through configure-time detection?  Could
produce unexpected interactions though...

Not critical for sure, but perhaps worth noting somewhere in the docs?
That libltdl's build support files are generated with version X, but the
above steps can be done to regenerate with version Y.  I can see this
being applicable to other similar packages that can be shipped as
