Personally I find these licence headers redundant with the declaration 
in the DESCRIPTION file.

As far as I'm concerned, unless otherwise specified, whatever is in Rcpp 
is GPL-2.


Now, are you sure you need linking?

One alternative I tend to use now is to define as much as possible (and 
perhaps all) in headers, and use the R mechanism if I really need to 
have a function in a .cpp file.

In Rcpp11, I've implemented this and I don't have the Makevars anymore. 
This makes extending easier as all the client package needs is to use 
LinkingTo to pull in headers from inst/include.
