21:35 Feature #718 (Closed): Insert calls to CheckForInterrupt

Current state is good enough, so closing. -
21:32 Design #934: MachineInt: change semantics?

# internal repr is @unsigned long@ and an extra bit to indicate that the true v... -
21:26 Feature #1702 (In Progress): Use C++ attributes

20:21 Feature #1218 (Closed): 32-bit or 64-bit preprocessor macro?
