We are using DEV-C++ 4.9.8.0 with Mingw/GCC 3.2
and use the Gtkmm binary for Windows (2.2.3)

I understand that! Personally, I would not do it even if someone pays me to do 
it!   

I have just tried to compile our project on Windows to see if there would be a 
lot of work to do to make it work.  But for now, I did'nt have to change 
anything to make it works.  These two problems are the only ones I have 
experienced, all other things are working properly ( which surprise me a lot 
on a platform like Windows... )
