Why not a recent release?

Okay, if you expect that to compile, you also need to update your own
knowledge of C++. I suggest you take a look at the book reviews at ACCU's
and use a prepackaged, binary release of the compiler, e.g. DevC++ or
mingw32.

#include <iostream>
#include <ostream>
int main() {
  std::cout << "Cheers!" << std::endl;
}

Two things:
1. Windows doesn't differ between .c and .C, you would be better off to use
the equally common .cpp for C++ code.
2. Never compile without warnings, for g++ 3 that would be -W -Wall and for
g++ 4 it would be -W -Wextra.

This installation technique was probably geared at DJGPP and rather suited
to DOS systems (it ran on win9x because they were largely DOS-based).

Use mingw32, this binary distribution already gives you everything,
including a compiler and some other tools. In any case you have everything
in order to compile programs together.
