5878,Detection of C++0x features broken with latest Intel compiler,sansottera@…,John Maddock,"prompt$ icpc -v
icpc version 12.1.0 (gcc version 4.4.5 compatibility)

Detection of C++0x features should *NOT* be base on STDC_HOSTED but on __GXX_EXPERIMENTAL_CXX0X__.

prompt$ icpc -dM -E test.cpp | grep CXX0X
#define __GTHREADS_CXX0X 1

prompt$ icpc -std=c++0x -dM -E test.cpp | grep CXX0X
#define __GXX_EXPERIMENTAL_CXX0X__ 1
#define __GTHREADS_CXX0X 1

prompt$ icpc -dM -E test.cpp | grep STDC_HOSTED
#define __STDC_HOSTED__ 1

prompt$ icpc -std=c++0x -dM -E test.cpp | grep STDC_HOSTED
#define __STDC_HOSTED__ 1

I classify this bug as showstopper since it prevents boost from compiling unless the user messes with boost's source code. The fix to apply is in boost/config/compiler/intel.hpp. The correct detection code should be:

#if (!(defined(_WIN32) || defined(_WIN64)) && defined(__GXX_EXPERIMENTAL_CPP0X__))
#  define BOOST_INTEL_STDCXX0X
