The following code can't be compiled with alpha version of gcc 4.3
from mingw (complete version information is at the end of this
message).

Code:
----------------
#include <vector>
using namespace std;

class A {
	int a;
	typedef std::vector<A> As;
	typedef As::iterator Iter; //Removing this line solves the problem
};

int main (){
	A();
}
----------------

A removal of line:
typedef As::iterator Iter;
enables successful compilation of this test case.

All other versions of gcc compile this code without problems.
