Sounds like you're trying to compile C++ code as C. Just because you 
invoke Clang as clang++ doesn't mean it runs in C++ mode, it only means 
it will link against the C++ runtime libraries. To actually compile in 
C++ mode, the file must have a C++ extension (.cxx, .cpp or .cc), or you 
have to override the language detection with the -x option.
