To expand/clarify, this is not a "nested declaration", but rather a redefinition of a variable that was declared in the same scope. Redefining variables in different scopes is fine. So if i were declared outside the scope of the for loop, this would be okay (this is called shadowing). Apparently, g++ up to 4.6 considered the scope of a variable declared in a for loop to be the "outer" scope, instead of the "inner" scope[1][2]. This explains the problem.
