Hi Guys,

 From about a week, I'm building GEOS 3.0.0 CVS a few times every day.
Recently, I started to build OGR (CVS) with GEOS 3.0.0 so I encountered 
a few issues I had to resolve.
The biggest change in GEOS that can be noticed is the reorganization of 
namespaces, new namespaces have been added.
So, some classes have moved as well.

Also, strk is working on splitting huge headers with into smaller, to 
not to include e.g. geos/geom.h in every file -> this shot cut down 
compilation time.

I'm trying to keep GEOS' makefile.vc synchronized with current changes 
strk is making. So, generally, makefile.vc is working but there are some 
issues possible in next days (e.g. movements in files) ;-)

Those are only a few changes that have taken place.

You can track GEOS progres bugs/fixes here:
http://postgis.refractions.net/bugs/index.php

So, if someone is interested in fixed up-to-date OGR for GEOS 3.0.0, 
please give me a not. I can provide version.
I'm not going to commit those changes to GDAL CVS because I'm not sure 
if OGR should integrate with GEOS 3.0.0 at this moment.
Or maybe there is dedicated branch of OGR for GEOS 3.0.0.
Frank: Is there any?

BTW, I'm building GEOS/OGR with VC++ 8.0, so I can provide VC++ 
solution/project files if anyone is interested.

Cheers
