iostream with gcc

[Peter M Lee <pml1 at york dot ac dot uk>]

I apologize for what is probably a silly mistake on my part. I am just 
starting to use cygwin. When I tried a simple program

#include <iostream>
using namespace std;

/**
* A simple program for demonstrating the basics of a C++ project.
*/

int main() {
   cout << "Hello, world";
   cout << endl;

 return 0;
}

with

$ gcc hello.cc

I got the following error message

/cygdrive/c/Users/PB2579~1/AppData/Local/Temp/cc7nz7Xj.o:hello.cc:(.text+0xd):
