Dear C++ standard watchers,

I have recently updated to the Microsoft Visual C++ version 5
compiler.
Its std C++ library has extra member functions in the templated
vector/map etc container classes (from STL), which were not in the
draft standard i saw or in the original STL..
These extensions provide methods for doing comparisions of entire
containers:
The following definitions for these addition are taken straight
from the MS doco.
Are these definitions part of the stardard c++ library????

namespace std {
template<class T, class A>
    class Cont;
//    TEMPLATE FUNCTIONS
template<class T, class A>
    bool operator==(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
template<class T, class A>
    bool operator!=(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
template<class T, class A>
    bool operator<(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
template<class T, class A>
    bool operator>(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
template<class T, class A>
    bool operator<=(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
template<class T, class A>
    bool operator>=(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
template<class T, class A>
    void swap(
        const Cont<T, A>& lhs,
        const Cont<T, A>& rhs);
    };

Thank you for information.

[etc.]

Yup, they're there. If you haven't already, I suggest downloading the
HTML form of the latest public document, and keeping it on your machine.
It's handy to have at your fingertips. It's at
