I am not sure what you are speaking about here: I just want the C++
compiled parser to not imposing any "using std::xxx" directives, which
happens if one includes C-compatibility headers.

EOF and NULL are C/C++ preprocessor macros, and thus do not even exist by
the time the C++ compiler start looking at the code: Thus they do not have
anything to do with namespaces, which is a C++ construct.
