[Rcpp-devel] Attribute does not compile with 'compileAttributes' but with 'sourceCpp'

[Dominick Samperi]

With Apple moving from gcc/g++ to LLVM/clang++ I guess it makes sense
for R/Rcpp to use the LLVM/clang++ tool chain eventuallly, but I don't know
if there are plans to do this. Otherwise, the R community would need to
support "MACtools" following the model provided by "Rtools" under Windows...
