Small patch for Rpy and recent R versions

After I asked on R-devel about the failure of Rpy to built with more recent versions of GNU R, I every now and then get a request for the patch mentioned in my follow-up on on R-devel.

To make life easier for everybody, and as the patch is so simple, here it comes:

--- rpy-0.3.1.orig/src/RPy.h

Thanks to Luke Tierney for the hint regarding Rf_onintr(). If you're into Debian, I also have a local package I could sent you. I'd upload it, but I don't really want to be stuck maintaining it when Rpy looks as if it has been orphaned by its original author.
