As long as you're trying to get the Intel compiler predefined macros
straight, please note that it defines __ICC only for the IA-32 version.
 For the Itanium version, the compiler defines __ECC. That is why they
deprecate both and recommend using __INTEL_COMPILER instead. I
understand that you may need to support all three for the purposes of
older versions of the compiler. I don't know when they introduced
