You didn't do this copy, but I'd appreciate it if you could reintegrate this with cp_parser_condition. I notice that there's already been significant drift: this copied code doesn't recognize {} initialization.

Can't the step size be a value-dependent expression like a template non-type parameter?

How is this different from any other for-loop?

A lot of code in this function tests for_keyword after the assert. A comment lower down says
+ /* Handle _Cilk_for here when implemented. */ + gcc_unreachable ();
So do we need the earlier assert? At least add a comment to it. Jason
