"basic_string" problem in libstdc++

[Fred Richardson]

It looks like basic_string is broken:

    %> cat foo.cc
    // #define NO_STRING

    #include <stdlib.h>
    #include <std.h>


    #include <stdlib.h>
    #include <iostream.h>
    #include <fstream.h>
    #include <string>

    //==================================================================
    //  main()
    //
    //  Program's main routine.
    //==================================================================
    int     main(int argc, char *argv[])
    {
        for (int i = 0; i < argc; i++)
        {
    #ifndef NO_STRING
            string      astr;
            const char* str = argv[i];
    #else
            const char* str = argv[i];
    #endif
            cout << "ARG " << i << ": " << str << endl;
    #ifndef NO_STRING
            astr = str;
    #endif
        }
        return 0;
    }
