11941	Use of overloaded operator== in BOOST_TEST() is ambiguous	kamo.tanabota@…	Gennadiy Rozental	"I'm unable to compile the following code due to ambiguity of opertor== overloads.

{{{
#define BOOST_TEST_MODULE mytest
#include <boost/test/included/unit_test.hpp>

struct S {
    template <class T>
    S(T&&) {}
};

bool operator==(S const&, S const&) { return true; }

template <class T>
bool operator==(T const&, S const&) { return true; }

BOOST_AUTO_TEST_CASE(test1)
{
    auto const s = S{""hoge""};
    BOOST_TEST(s == 4);
}

}}}

This seems to happen if there is an overload taking a template parameter for the left operand.

Using boost::iterator_range, instead of the class S, results in same issue.
