patch against 2.9.0 and c++

[Peter Ernst]

To my knowledge "string" is NOT a reserved word in C++.
You run only into problems, when copying the std:: namespace onto the
Emboss namespace with "using namespace std;".

>From "The C+ + Programming Language Third Edition: by Bjarne
Stroustrup:

   You must either use the std:: prefix or make every name from std
   global (§8.2.3). For example:

   #include<string>     // make the standard string facilities accessible

   using namespace std; // make std names available without std:: prefix

   string s = "Ignorance is bliss!"; // ok: string is std::string

   It is generally in poor taste to dump every name from a namespace into
   the global namespace.
   [....]
   A using directive makes names from a namespace available almost as if
   they had been declared outside their namespace.

Kind regards,

     Peter
