5661,"Scoped enums used for Intel compiler but /Qstd=c++0x not used, causes error with operations.hpp",Brandon Hewitt <brandon.l.hewitt@…>,John Maddock,"I'm using Intel C++ Composer XE 2011 update 4 (i.e. icl 12.0) for Windows on Intel 64 with Visual Studio 2010.  When trying to build Boost 1.46.1 with the following command line:

.\bjam stage --toolset=intel address-model=64 variant=release --
build-type=complete threading=multi --without-wave --without-python --without-mpi --without-graph --without-graph_parallel

I get a problem compiling v2_operations.cpp:

compile-c-c++ bin.v2\libs\filesystem\build\intel-win\release\address-model-64\threading-multi\v2\src\v2_operations.obj
'""C:\Program Files (x86)\Intel\ComposerXE-2011.4.196\bin\intel64//iclvars.bat""' is not recognized as an internal or external command,
operable program or batch file.
icl: command line remark #10010: option '/Og' is deprecated and will be removed in a future release. See '/help deprecated'
icl: command line warning #10148: option '/Oy' not supported
icl: command line remark #10010: option '/Op' is deprecated and will be removed in a future release. See '/help deprecated'
v2_operations.cpp
.\boost/filesystem/v2/operations.hpp(511): error: expected either a definition or a tag name
      BOOST_SCOPED_ENUM_START(copy_option)
      ^
This happens because BOOST_SCOPED_ENUM_START(copy_option) is preprocessed into:

  enum class copy_option

which happens because of the following code in boost\config\compiler\intel.hpp:

#if defined(_MSC_VER) && (_MSC_VER >= 1600)
#  define BOOST_INTEL_STDCXX0X
#endif

and then later:

#if defined(BOOST_INTEL_STDCXX0X) && (BOOST_INTEL_CXX_VERSION >= 1200)
#  undef  BOOST_NO_RVALUE_REFERENCES
#  undef  BOOST_NO_SCOPED_ENUMS
<snip>

The problem becomes then that the assumption is made that the compiler will support C++0x, but the Intel compiler requires the /Qstd=c++0x command line option to support this mode, and this is not used when v2_operations.cpp is compiled.  If I add /Qstd=c++0x to intel-win.jam, then the build works.
