Agreed, Joseph.  That's what we discussed.  We just wanted to give the 
build/configure guys a day or two for the libtool update, not making that 
one more tricky in case it finally happened, while not waiting longer 
before fixing the release branch.  So, technically you are absolutely 
right, and we'll close that window soon unless the wholesale libtool
update happens earlier.
