Why is that?? I've had this same problem when compiling stuff on a 3b1. Like, what exactly is it about the optimizer that's broke (I'm assuming that it's the same problem). The message I got on the 3b1 was [loop?] "branch label too far" -- which I thought was pretty weird but I wrote it off to the 3b1's 68010 which has loop instructions at the uP level.
