Now, of course, anyone who's got a religious rather than technical objection against something called "x86"... if they can find they don't hate it when they call it "x64", I say go for it. And while you're at it, stop being insane. The instruction set hasn't mattered since whenever it was in the 1990s that compilers just got better than people (if you want to say 99.9999% of the programmers out there, I'll concede there may be some joker in a cave somewhere who can code better than the compiler... not more accurately, not faster, but better. At least until I change from one x86 chip to another).
I think the choice of the XCore chip using the LLVM (Low-Level Virtual Machine) toolchain was a good transitional state. Soon it may be possible to go cross-platform in the way that Java would have done early on if it hadn't sucked so bad at first. And best of all, LLVM is funded by Apple, Google, and Adobe.
The one problem is that the supervisor-level stuff on a Kernal needs to be done in assembly rather than C. Perhaps porting LLVM to AROS would be a better idea in the long run.
