Hmmm...there's a line in ltmain.sh that says:

        -allow-undefined)
         # FIXME: remove this flag sometime in the future.
         $echo "$modename: \`-allow-undefined' is deprecated because it 
is the default" 1>&2
         continue
         ;;

Actually, libtool.m4 is an original file.  It isn't generated from 
anything AFAIK.  Anyway, I updated to the most recent libtool CVS, and 
whaddaya know -- almost all of your patches have made it in.  The 
attached patch is all that's left "outside" (and it also includes the 
patch you just posted).

I'll whip up a new libtool-devel package soon.  What's the story with 
the automake-1.6 package I put up?  Had a chance to play with it yet?
