It didn't get to "work", it broke building.  (The frighting part is that my 
patch at http://busybox.net/downloads/qemu applied to your version without 
rejects, but although that helped it get farther, it didn't finish.)

I just did a standard "./configure --shutupaboutthecompilerversion; make; make 
install".  (x86 is the first target I'm interested in, as it's the easiest to 
test and you said it's using at least some of the new code...)
