No, too many users still have 10.5 and 10.6 has dropped ppc support, so we don't plan to drop Leopard support anytime soon.

No, even R-devel is build with 10.5 target - R version and OS have nothing it common. Windows is split only because of 64-bit support which is not available in older OSes - that is the only reason why the builds are not on XP anymore, they would be otherwise.

Well, I don't think that helps in any way - the test will still fail for all 10.5 users. Why don't you just fix the test? It's up to you, but removing Rcpp from CRAN won't help anyone (well, almost ;)).
