Hi!
I'm using crossdev for creating an AVR toolchain. I know gcc 4.6.2-r1 is the latest version that supports cross-compiling. However, when I try to compile it using crossdev, it has some fails in the code. I applied a patch I created: http://pastebin.com/vrKbRp98, and the code was successfuly patched, but then gave me another error, and a segmentation fault.
By now, I'm using gcc-4.3.3-r2, what's pretty old.
