| 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 ;)).

I CC'ed you on a detailed post I sent to our internal rcpp-core list. It
smells like a compiler issue to me. 

What boolean test for 'am I on OS X 10.5' can you suggest?  I will then
disable the test.  Maybe Ken or Baptiste can test that and I would submit the
thusly amended tarball as 0.9.2 so the we all can get back to peace, love and
apple pie rather than fighting Steve Jobs' insistence on an outdated compiler.
