Summary: gcc 3.4.1/iostream stumbles over C99 definitions

Initial Comment:
I just tried the latest gcc 3.4.1 (3.4.0 candiate
worked fine for me before) and iostreams seem to be
very broken. This works on 3.4.1/Linux without a problem.

C:\home\h_hoffstaette\Projects\cpptest>type Main.cpp

using namespace std;

#include <iostream>

int main(int argc, char** argv)
{
    cout << "Hello World!" << endl;
}


C:\home\h_hoffstaette\Projects\cpptest>g++ Main.cpp

Thanks for looking into it. I already suspected a botched
install (not surprising after ~5 updates of gcc in Dev-Cpp)
and reinstalling the latest mingw-runtime headers
reproducably fixed the problem. I'll creep back into my cave
now.
A big Thank You for mingw-gcc, btw. :)
