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 
__INTEL_COMPILER.
