[Bioc-devel] tokay1 C++14 compiler

Windows (and macOS) CRAN packages are installed as binaries (as experienced by the typical user), so don't need compilation-- Rstan is built by CRAN through whatever magic / agreement.

The paragraph at the very end of

   https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Using-C_002b_002b14-code

suggests

Note that g++ 4.9.x (as used for R on Windows at the time of writing) has only partial C++14 support, and the flag to obtain that support is not included in the default Windows build of R

so my understanding of this is that CXX14 is not supported on Windows. The options are either to revise your code to avoid CXX14 or to anticipate that your package will be 'Unsupported on Windows' (thereby losing 1/2 your user base).

The expert on this (Herv?) will not be back for several days.

     What's weird here is that you supposedly depend on rstan which also
     requires a C++14. How can the build system have that package installed
     without having a compliant compiler?
