Btw.: Andrew Haley (from RedHat) comments on my question on the GCJ IRC 
channel:

aph: There's some magic in Win32 to extend the size of a stack segment
aph: I can't remember the command
egholm: but you're right, the problem has first entered after adding 
some more .o files
aph: we had to do it with Win gcc cross compilers

Hence, it seems that there is some solution somewhere out there (unless 
he remembers wrong ["aph: I have garbage collected knowledge of unfree 
OSs from my mind"])...
