Milestone:  To Be Determined  |   Component:  config

------------------------------+---------------------------------------------
 The recently released Intel C++ Compiler has a new option -use-clang-env
 (OS X version only). This cause icpc to define the macro __clang__ and use
 Clang's headers etc. I haven't found any particular effects at the moment.
 Maybe they are planning switching to libc++ on Mac OS X as libstdc++ will
 not be distributed on OS X anymore in the near future.

 Anyway, the problem is that with this macro defined,
 select_compiler_config.hpp will select Clang instead of Intel icpc as
 compilers. Further, even icpc has this macro, it does not have all the
 clang's __has_features(...) macros defined, and thus this wrong selection
 cause compilation error.

 The fix is very simple, simply test __INTEL_COMPILER before __clang__. The
 fixed header is attached in this report. I am not aware if there are any
 other compatibility problem with this new compiler yet. However, this one
 need immediate fix.
