Nope.

Because nobody has built R itself with VS/VC++ even though people have been
trying for a decade. [ Revolution's initial win64 port used the Intel
compiler. ]

And given that R doesn't built that way ... you end up an R binary built with
MinGW that will not be able to load your VS built library. 

So why bother?

I think you can do one better one each -- 0.2.1 and 0.8.1.  That version I
had working too, but of course using MinGW.  We would appreciate debugging
help in restoring that functionality to current versions.  
 
| I greatly appreciate your help in this regard.

We make it clear how we use R and Rcpp, and R Core makes it clear how CRAN is
built so that many other users can take advantage of it.  You are out of
scope. So sorry -- but you are on your own.  

Good luck.

Dirk
