[boost] [spirit] [1.33.1] file_iterator needs workaround for VC8

23 Dec 2005

      Hi,

Under VC8 Express Edition:

  #include <functional>
  #include <boost/spirit/iterator/file_iterator.hpp> // greeting

  namespace your {
    struct plus { };
  }

  namespace my {
    using namespace your;
    struct A : plus { }; // error C2872: 'plus' : ambiguous symbol
  }

I don't know what happens,  but 'using namespace std;' at
<iterator/impl/file_iterator.ipp:line41> does something bad.

Simplified Code:

  namespace standard {
    struct plus { };
  }

  // almost like 'using namespace standard' under vc8?
  namespace fileiter_impl {
    // 'using-directive' here
    using namespace standard;

    // 'class template' here
    template< typename CharT >
    class std_file_iterator { };
  }

  namespace your {
    struct plus { };
  }

  namespace my {
    using namespace your;
    struct A : plus { }; // error C2872: 'plus' : ambiguous symbol
  }
