Ok, I'm done with that for now. There's more cruft to clean up, but that's for 
another day. Also, on and off, I'm working on getting rembedinternal.cpp to 
compile on win32. However, those changes should be relatively easy to merge 
with whatever will be needed for your debugger.

I took a quick look, now, and it's nice stuff, but the value for RKWard is 
limited:
- We only need a rather "narrow" interface to R. Our goal isn't to do speedy 
calculations in C++, but to add a GUI on to of R. Hence, for most things that 
we want to put into R-space, we can use plain R syntax.
- The other way around it's more interesting, and I'll take a closer look at 
the date/time classes one day. However, the place we really need this is the 
data editor, and we're generally well advised to try to use QStrings/QLists 
and such, there (+ we need to implement all the range checks and goodies from 
rcpp, in the data model, anyway). (core/rkvariable.cpp, our main data-storage 
for the data editor will need to be revised a lot, as well, but probably 
towards using Qt-classes).

So it seems like a good place to look at, when in doubt about how to deal with 
some R structures. But not something that is of much *direct* use to RKWard, I 
think.
