The string class should have come with the standard C++ libraries installed
with your C++ compiler. For instance, on my RedHat 5.2 machine, I have:
$ cat /usr/include/g++/string
// Main header for the -*- C++ -*- string classes.
#ifndef __STRING__
#define __STRING__
#include <std/bastring.h>
extern "C++" {
typedef basic_string <char> string;
// typedef basic_string <wchar_t> wstring;
} // extern "C++"
#endif
