The Sun FORTE also has problems with this (though it barks at a  
different place). Since you have cvs access: could you just comment out  
the lines containing 'sigc::ref("\n")' in test_lambda.cc adding a  
comment that this doesn't work with the Sun FORTE C++ and the Compaq C+ 
+ compiler, please?

Of course any new ideas how to handle constant string arrays are  
welcome!

Thanks,
