I've hosted gcc on mine, mainly as a code generation correctness check... It's nice having a simulator and enough address bits, you can just plop down yet more memory and presto, everything just works. The more annoying aspect is having to wire up stat and readdir for sim. Fork and exec, are more trivial by comparison. Some gcc ports might not have enough address bits, that might be the only hard requirement that one cannot fudge.
