Default g++ 4.7.1: noexcept for the move constructor

In g++ 4.7.1, it seems that the noexcept keyword is mandatory for the move constructor of a class.
For instance, without noexcept, the container vector calls the standard copy constructor instead of the move constructor when an internal reallocation is needed (push_back).

Default

I'm not sure if that's correct behavior. For example, the implicitly declared move constructor doesn't specify noexcept.
The C++ standard says:
Quote:
The implicitly-declared move constructor for class X will have the form
X::X(X&&)
