It is known there.  This solution removes duplicate entries,
but causes problems for other platforms.  It's very easy to fix
in my "binary version" of libtool, but when you constrain yourself
to basic Bourne shell with no function capability, you make solutions
much more difficult for yourself.  In any event, I'm forwarding
to the libtool list to make it clear another derrier got bitten.....

David: Thanks for the man page patch.  Applied.
