#13181: Boost test can't compare classes which have begin and end but not
const_iterator

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  test
  Version:  Boost 1.65.0      |   Severity:  Regression
 Keywords:                    |
------------------------------+-------------------------------
 The following code:
 {{{
 struct s
 {
         const int *begin() const;
         const int *end() const;
 };

 bool operator==(s,s);
 std::ostream &operator<<(std::ostream &out, s);

 BOOST_AUTO_TEST_CASE(foo)
 {
         s s1;
         s s2;
         BOOST_TEST(s1==s2);
 }
 }}}

 When compiled in C++14 mode by gcc or clang, fails because `s` does not
 contain member types `const_iterator` and `value_type`.  This works in
 C++03 mode, and it worked with boost 1.64.

 The attached patch fixes the issue.
