Milestone:  To Be Determined           |   Component:  config

 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
 #endif
