Sure, why not, the more the merrier, as long as it doesn't get in the way of other stuff, I won't protest. But please don't confuse people: you are talking about a powerpc-linuxspe compiler, not e500, which is supported just fine by current GCC trunk still, and does not have such limitations :-) Segher
