/* The C++ standard is evolving to allow attribute hints in a
   compiler-independent manner.  In C++ 2011 support for noreturn was
   added.  In C++ 2014 support for deprecated was added.  The Octave
   code base has been future-proofed by using macros of the form
   OCTAVE_ATTRIBUTE_NAME in place of vendor specific attribute
   mechanisms.  As compilers evolve, the underlying implementation can
   be changed with the macro definitions below.  FIXME: Update macros
   to use C++ standard attribute syntax when Octave moves to C++ 2011
   standard.  */
