thank you very much for your help. i've now managed to compile and LINK 
a more or less simple gtkmm application. At first i tried to simply 
upgrade to gcc 3.4.2 and then to compile and link from the commandline. 
but that didn't really work. Then i installed dev-cpp together with 
mingw-3.3. I was succesfull in building a test application. but the 
generated exe file  didn't really do much more than producing a 
segfault. After that i remerbered you telling me to try gcc 3.4.2. i 
removed dev-cpp, installed mingw with gcc 3.4.2 and then dev-cpp again 
without mingw. that seems to work better. the segfaults are gone and a 
window appeared.

Now the problem that remains is:
In this window i've a Gtk::Layout which should normally do/draw 
something that depends on mouse events. While the contents of my layout 
look like they should, it remains completly irgnorant to mouse events.

besides i noticed some things which are not easy to understand:
gtkmm only works for me if i install it directly into my dev-cpp folder; 
and even if dev-cpp is able to compile and link a gtkmm-app this is not 
neccesairly true for compiling and linking in the MSYS/native M$ shell 
using pkg-config.
