Hi,

The call of istream::tellg() on an input file stream causes a move of
the actual reading position. This seems to happen in connection with the
use of istream::get(char).

Test program:------------------------------------------------------
#include<fstream.h>

void main()
{
  ifstream fileS("mbinput.txt");
  char c;
  streampos pos;
  while (fileS)
    {
      fileS.get(c);
      if (c=='=') {pos=fileS.tellg();};
      cout << c;
    };
  cin >> c;
}

-------------------------------------------------------------
On the first ocurrence of '=' in "mbinput.txt" the current read position
jumps forwards some characters. Is this a bug?

Thanks for help (if possible as email to me)

Boris.
