 State-Changed-Why:
     Your example is not self-contained. Here's my best guess:
     
     // libstdc++/2897
     #include <iostream>
     #include <fstream>
     
     int main()
     {
       using namespace std;
     
       const char* dateiname = "tmp";
       ifstream eingabe(dateiname);
       if (!eingabe) 
         {
           cerr << "Datei '" << dateiname << "' konnte nicht geoeffnet werden!\n";
           cerr.flush();
           exit(5);
       }
     
       cerr << "Position: " << eingabe.tellg() << "\n"; 
       cerr.flush();
       eingabe.seekg(0,ios::end);
     
       return 0;
     }
     
     
     This fails to produce an error though:
     
     %./a.out 
     Datei 'tmp' konnte nicht geoeffnet werden!
     
     
     This may be because the c++ library being used is a complete re-write of what you've been using with gcc-2.53.
     
     Please try some example code using the codesourcery.com trial compilation page, and let me know if the problem is indeed fixed.
     
     thanks,
