R Project Updates

Updates from R Core:

• Packages which register native routines for .C or .Fortran need to be re-installed for this version (unless installed with R-devel SVN revision r72375 or later).

• An alternative compiler for C++11 is now specified with CXX11, not CXX1X. Likewise C++11 flags are specified with ‘CXX11FLAGS’ and the standard (e.g., -std=gnu++11 is specified with CXX11STD. The variables with prefix CXX1X are defunct.

• The tests for C++11 compliance are now much more comprehensive. For gcc < 4.8, the tests from R 3.3.0 are used in order to maintain the same behaviour on Linux distributions with long-term support.
