Yes, replacing __ICC with __INTEL_COMPILER should work fine. It turns out
that __ICC is only defined on ia32, not defined on ia64. The manpage says
it's there for legacy reasons only, __INTEL_COMPILER seems to be the Right Way.
I verified that it's defined on both platforms, and also for the older icc 6.0
compiler. __INTEL_COMPILER=800 for version 8.0, 600 for 6.0 and so on.
