I just tried to build Rcpp with __FreeBSD_kernel__ on a recent FreeBSD 10.0-CURRENT (newest developer version) and it does not resolve. On 'pure' FreeBSD there is only __FreeBSD__ defined, not a kernel specific version. I think there are much more 'pure' FreeBSD systems than linux ones with FreeBSD kernel, so it would be nice, if you would pick up at least the __FreeBSD__ symbol.
