To save a lot of effort have a look at Boost's compiler detection bits
as depending on the flags some compilers 'pretend' to be other ones
right down to #defines ... and bugs! e.g.

// Is this Intel's compiler
#if defined(__INTEL_COMPILER)
#  define INTEL_CXX_VERSION __INTEL_COMPILER
#elif defined(__ICL)
#  define INTEL_CXX_VERSION __ICL
#elif defined(__ICC)
#  define INTEL_CXX_VERSION __ICC
#elif defined(__ECC)
#  define INTEL_CXX_VERSION __ECC
#endif
