The svn version of Rcpp works on windows (at least on my copy).

As Dirk said, we do definitely want Rcpp 0.8.4 before useR, preferably 
before the end of this week.

I'm not sure why it does not work on the ppc arch on OSX, we might be 
using a compiler feature that was introduced after moving to intel ... I 
need to have a closer look and perhaps involve the r-sig-mac list.

solaris is something else entirely. We might need more iterations.
