What kind of problems are you having with the executables? I've not  
built gcc recently, but we are using gcj 4.0.2+patches for our  
product, and it is surely working (except for stack unwinding). I can  
send you 4.0.2 patches if you are interested.

This seems tied to some changes in the boehm gc codebase that has  
occurred after my patch submission. I'll give it a try when I have  
some spare time, but at the moment I'm quite busy.

As I said before, 4.0.2 (and probably 4.0.3) can be patched  
successfully. Don't know about 4.1 branch (probably yes, choosing the  
right libffi patch).
