Can someone tell how to fix my visual c++ so it can discard this error
message.
I get this error message
error C2593: 'operator >>' is ambiguous
But I do not when I am on my mandrake linux platform. Why is this, a bug in
visual c++ ?

Possibly a bug in VC++. Possibly a bug in g++.
How the heck could anybody guess when your code is secret?

Post the code!!

My guess is that you are mixing correct headers (like <string>) with
incorrect headers (like <iostream.h>). In other words your code is at fault
not g++, or VC++. No C++ headers (except those that C++ gets from C) have a
..h

#include <iostream.h> // wrong
#include <iostream> // right

#include <fstream.h> // wrong
#include <fstream> // right

#include <string.h> // OK, C string handling
#include <string> // OK, C++ string handling

Gosh my psychic powers are good today.

I think it's a bug in VC++/6.0, though I may be wrong. I overloaded
the insertion operator for my own cl***, Questions, once. I placed a
number of such objects in a "list" container, declared an iterator,
moved it to point to the object that I wanted it to, dereferenced it,
and called

cout << *iter;

g++ didn't complain. VC++/6.0 flagged it as ambiguous.
