а такое показывать не стыдно?

void
AuxFunc::homePath(std::string *filename)
{
  char *fnm = getenv("USERPROFILE");
  if(fnm)
    {
      *filename = std::string(getenv("USERPROFILE"));
    }
  else
    {
      fnm = getenv("HOMEDRIVE");
      if(fnm)
    {
      *filename = std::string(getenv("HOMEDRIVE"));
    }
      else
    {
      fnm = getenv("HOMEPATH");
      if(fnm)
        {
          *filename = std::string(getenv("HOMEPATH"));
        }
      else
        {
          fnm = getenv("HOME");
          if(fnm)
        {
          *filename = std::string(getenv("HOME"));
        }
          else
        {
          fnm = getenv("SystemDrive");
          if(fnm)
            {
              *filename = std::string(getenv("SystemDrive"));
            }
          else
            {
              std::cerr << "Cannot find user home folder" << std::endl;
              exit(1);
            }
        }
        }
    }
    }
  toutf8(*filename);
}

и там ведь весь код такой
