My build of sigc++ does not seem to export export any 'nil' or 'none' 
symbols. This seems to imply that 'nil' is not part of the sigc++ ABI.

But what you are seeing seems to imply that 'nil' is part of gtkmm's 
ABI. How annoying.

I don't have a solution to that problem so far, I'll try to think some 
more about this. Thanks,
