[RFC] Non-conforming begin() and end() iterators in <set> end <multiset>?

[Paolo Carlini]

Hi,

in this message, which also contains a testcase:

    http://gcc.gnu.org/ml/gcc-bugs/2003-02/msg01402.html

Uwe Sassenberg pointed out that in <set> and <multiset> we
have for begin() (same for end() and the reverse versions):

  iterator begin() const;

instead of the couple (23.3.3):

  iterator begin();
  const_iterator begin() const;

Is our implementation ok?

Thanks for any explanation,
Paolo.
