226595515c* refactoring: idents don't need inheritance * refactoring: adding an IdGenerator (part 1) * refactoring: adding an IdGenerator (part 2) * refactoring: adding an IdGenerator (part 3) * refactoring: adding an IdGenerator (part 4) * refactoring: adding an IdGenerator (part 5) * refactoring: adding an IdGenerator (part 5) * IdGenerator must be a ref type; hello world works again * make bootstrapping work again * progress: add back the 'exactReplica' ideas * added back the missing exactReplica hacks * make tcompilerapi work again * make important packages green * attempt to fix the build for 32 bit machines (probably need a better solution here)
