Really. Hm. There isn't more than that? I mean GCC4 doesn't generate the 
text segment symbol anymore.


Either way, this is not likely to change in the future is it? The git 
tree will need to support both a generic GCC4 build and the old build of 
the toolchain which has been floating around for a while.
