Hi Masahiro,

+       #elif defined(__INTEL_COMPILER)
+       /* How to get the version of intel compiler? */
+       ICC     0               0               0

According to Intel documentation[1], this should do the trick:

    ICC     __INTEL_COMPILER  __INTEL_COMPILER_UPDATE
__INTEL_COMPILER_BUILD_DATE

I don't have the compiler installed, but I tested this on godbolt[2] and
looks fine to me. What do you think?
