Yes. 

Cross-compiling can work, but some of the version of gcc are more finicky
than other.  Eg Jeroen used the different mingw cross-compiler version on
Ubuntu to build a Windows library of Protocol Buffers which he then made
available to CRAN / win-builder.  So now we have Windows builds of RProtoBuf
too.  

But he had to try three different ones. As I recall the 4.7.* variant worked,
the others lead to errors once used on Windows. But you'd have to ask him.

We are a little off-topic now as far as 'how do I use Rcpp' goes.
