Charles Wilson,

Could you look at the problem discovered in the thread below and give us a
comment?  Thanks.

I'm not an autotool expert, but:

These are just warnings, so I think this part worked fine.  I guess the
ddd people should clean these up?

Here is where we should have stopped, although I don't know how to do
that with autoreconf.  The following are errors from subdirectories that
use older (circa 2.13) autoconf scripts.  autoreconf does not support
mixed versions, I guess?

So, if this hasn't left your tree broken, I think it would test what I
wanted.  You should now have libtool 1.5 for the main ddd tree.  I think
it would fix this.

New in 1.5: 2002-04-14; CVS version 1.4e, Libtool team:
* Support auto-import patch to binutils on cygwin for much improved dll
  support.
