CGAL users discussion list

I am migrating my project (VC++ .NET 2003) from CGAL3.2.1 to CGAL3.3. 

When I rebuild my project(using taucs libs packaged in CGAL) on the new CGAL, 
the linker complained that there are redefinitions of 
_cgal_taucs_available_memory_size:

Mesh.obj : error LNK2005: _cgal_taucs_available_memory_size already defined 
in ChildFrm.obj
MeshDoc.obj : error LNK2005: _cgal_taucs_available_memory_size already 
defined in ChildFrm.obj
MeshView.obj : error LNK2005: _cgal_taucs_available_memory_size already 
defined in ChildFrm.obj
FormView.obj : error LNK2005: _cgal_taucs_available_memory_size already 
defined in ChildFrm.obj

Even though I just include the "Taucs_solver_traits.h" in the 
enrich_polygon.h, (included by MeshDoc.h, while MeshDoc.h is included by 
other .cpp) and do nothing, the link errors still appear! But the same 
project can be compiled and linked without error when built with CGAL3.2.1!

The new CGAL provides the auto-link mechanism for libraries, including taucs. 
Does the problem have something to do with the auto-link? How do I get rid of 
the link errors?

Thank you!
