Deal.

Thanx.   That seems to do it for me.

Lovely.  That should reduce the pain.  (Or at least trade it for a known
form of pain. :-)

Once the treee builds again, I'll take this one back up.  I observed
this on the lone (sigh) day that it successfully built for me.

Agreed.  That should always be our goal as developers.  When we succeed,
it's great.  But I have a suspicion that debugging this stuff in the
field is going to be a patience-trying experience.  We could have
targets now that must have libtool ported to them before the tree will
bootstrap.  Perhaps that's a necessary cost on the road of progress.

Thanx for the response.
