That is already taken care of in SVN for Rcpp:

2013-01-15  Dirk Eddelbuettel  <edd at debian.org>

	* src/api.cpp (Rcpp): Commented-out coerce_to_string() for real and
	complex arguments as R-devel (as of today) dislikes use of non-API
	functions Rf_EncodeComplex’, ‘Rf_EncodeReal’, ‘Rf_formatComplex’ 

	* .Rbuildignore: Added inst/include/Rcpp/preprocessor and
	sugar/functions/impl which are currently empty directories

	* src/Timer.cpp (Rcpp): Avoid a 'long long' warning from a const

R Core added this test around Jan 13 or 14, or /way/ past our last release. 

So there is nothing we could have done in December when we released, and
there is nothing to do here until our next release -- but I successfule urged
Kurt to update "his" copy of Rcpp to our SVN which he did in order to
suppress this.

In short, gRbase is an innocent bystander and victim of a very zealous
warning.  Update Rcpp and this will be quieter.
