Ideally we should see the version of the actual compiler but this is 
lower prio right now.

$ clang -v
Ubuntu clang version 3.0-6ubuntu3 (tags/RELEASE_30/final) (based on LLVM 
Target: x86_64-pc-linux-gnu
Thread model: posix

$ clang -dM -E -x c /dev/null | fgrep '3.0'
#define __VERSION__ "4.2.1 Compatible Ubuntu Clang 3.0 
#define __clang_version__ "3.0 (tags/RELEASE_30/final)"

We should use __clang_version__ if defined, and if not we can use 
__GNUC__*. But before fixing this, the same should be determined for icc.
