Yeah, it may seem like the signal handler return types changed at some 
point, although I though they shouldn't based on the fact that GTK+ is 
supposed to have a completely stable API...

I'm not sure what GTK+ version I tried to build with, as I'm on a 
different machine now, but I would assume it was more or less the latest 
and greatest. What version I had last time it worked is probably 
impossible to tell now...

That's not really the question here. We're talking about a special build 
system on MacOS X, which is supposed to support a "package" for the 
Gtkmm 2.0 API, only now this support is broken. There's still a question 
of whether anybody will actually use it, of course, but gtk and gtkmm 
1.2 are also supported, if you know what I'm saying...

In any case, my question is really what I generally need to change (i.e. 
which source files etc.) in order to fix problems like this. Is there 
some sort of guideline etc?
