Thank you, Damien. Obviously, the FORTE compiler accepts the operator  
overloads if they take every argument as a const reference. No compiler  
check is needed at all! I'm currently building a new test tarball and  
will upload it withing the next hour to:

www.hippogriff.de/libsigc++-2.0.4-test1.tar.gz

Please try this one and post the compiler output as usual.

Cheers!
