You probably need to special case `9998` and `9999` - which is fine because these values don't change. For released versions (at least for the current way of defining the macros) the following should be possible (not tested):

  #define KMP_COMPILER "Intel C++ Compiler " stringer(__INTEL_COMPILER / 100) "." stringer(__INTEL_COMPILER % 100) "." stringer(__INTEL_COMPILER_UPDATE)

Maybe you need to assign the temporary values to other defines for the macro magic to work, I'm not too familiar with how it works...
