[Dev-C++] problems after upgrade

[KFC <KFC...@et...>]

Hi all,
  I upgrate my Devcpp to the newest version. I found that so many
function doesn't work.

For the simplest example, I wrote

#include <iostream>

void main(void)
{
  std::cout << "hello";
}

and compile. IT FAILS!!!! and report that something wrong with the iostream.
What is going on?

By the way, I find that the function of importing VC program doesn't
very work. Although it can import a project, but compile fail.
