Yup. Declaring it is easy. And the consequence _can_ (for now) be that you may not be able to build on Windows. The g++ 4.6.* compilers supports a subset of C++11 only. I declare 'CXX_STD = CXX11' in packages RcppAnnoy, RcppBDT, RcppCCTZ, RcppCNPy, RcppTOML -- and of these RcppAnnoy, RcppBDT and RcppCNPy *do* create Windows binaries. Whereas RcppCCTZ and RcppTOML use 'real' C++11 with features not supported by this old compiler so they exist on Linux and OS X only. | Q2: Are C++11 features available on Windows? | A2: Not yet. Release 4.6.3 includes limited support for C++11 features. | Again, the "Writing R Extensions" manual will give you more details, | with a link to a page describing what features are available.

However, it is not sufficiently | stable on Windows. It depends. It is not black/white even if some people insist on portraying it as such. Many features were added incrementally. g++-4.6.* has C++0x with some things, g++-4.9 adds quite a lot more and works for all I do. At work we sometimes rely on C++14 already and use g++-5.2. So you need to tell us what it is you want to do, or just try it, and the compiler _currently in use_ may fail. With some luck we may get g++-4.9.* on Windows with R 3.3.0. The error you showed from spanmatcher appeared to be a _linker_ error not a compiler error so something else may be going on there.
