This was a bug in the documentation, which has been fixed already (see here:

http://boost-consulting.com/boost/libs/wave/doc/quickstart.html). 

It should be:

    //  The template boost::wave::cpplexer::lex_token<> is the 
    //  token type to be used by the Wave library.
        typedef boost::wave::cpplexer::lex_token<> 
            token_type;
    
    //  The template boost::wave::cpplexer::lex_iterator<> is 
    //  the lexer type to be used by the Wave library.
        typedef boost::wave::cpplexer::lex_iterator<
            token_type> lex_iterator_type;
        
    //  This is the resulting context type to use. The first 
    //  template parameter should match the iterator type to 
    //  be used during construction of the corresponding context 
    //  object (see below).
        typedef boost::wave::context<
                std::string::iterator, lex_iterator_type>
            context_type;

Which compiles fine.

Thanks for reporting!
