I have recently had a strange compile error that I cannot seem to figure out. It started propagating on some of my projects for no reason...even projects that I have not changed. At first i thought it was just a random element, but it seems to be tied to mscv++ 7.1 and iostream and fstream. Now I could be wrong on this but that is what I have come down to. Now the errors I am getting is as follows:

Now this is what I am trying to comile... the project I am working on is far more complex but as a test i slapped together this quick example which use to compile fine in vc++ 7.1 but now does not.
#include <fstream>
#include <iostream>
using namespace std;
void main()
{
fstream file;
file.open("test.txt", ios::out);
file << "example" << endl;
file.close();
}
I also tried compiling the code under vc++ 6 and it compiled fine and ran fine. This is a strange because my larger projects have started running into this compile error as well. For instance I was working on my project and created a new class and compiled fine...went to implement the class in another and started getting the compile errors. I back out and commented out the implementation, but the errors remained. On the same code that compiled fine a moment ago!
I have tried un-installing and re-installing msvc++ 7.1 to no avail. I have searched through numerous google search pages trying to find anything on the probelm. The closest I got was the exact same errors and the only response saying it looked like a compiler glitch, but he didn't have an answer.
I also searched throught the msdn database and found nothing. Please, if anyone has any idea please help. Thanks.
