Hi,

Looking at CGAL/General_polygon_set_2.h line 58, in CGAL 3.3.1 I see 
what appears to be an omission:

The definition of "self" is templated _without_ the Dcel_ template 
parameter.

This means that the expected "other" GPS for a difference on self 
operation (e.g. gps.difference(other)) is a GPS with the default dcel, 
EVEN if I have instantiated the GPS with a custom dcel.

In my case, this is exactly my situation..all of my GPS's are templated 
with custom DCELs...adding Dcel_ to the self typedef fixes the compile 
problems.

(This is definitely a weird use of the general-polygon-set class! :-)

I can file a bug or send a modified source file if needed/desired.

This is the SVN info for the version of the file I have:

// $URL: 
svn+ssh://scm.gforge.inria.fr/svn/cgal/branches/CGAL-3.3-branch/Boolean_set_operations_2/include/CGAL/General_polygon_set_2.h

$Date: 2007-03-17 09:50:51 +0100 (Sat, 17 Mar 2007) $

Thanks!!
Ben
