I'm having minor issues here; I've had to change it a bit but I'm
still getting regressions.  Hopefully I'll have something this evening.

I'm working on integrating tradcpp to avoid this mess.  I should be
able to have it for 3.2.  That's my goal, at least.  It'll share most of
its code with existing cpplib; and just have some lexing code, #define
parsing, and macro expanding to itself.

That's the plan, at least.

Thanks for the patch; I had this on my to-do list.

Neil.
