boost_test_print_type is not considered when printing out values with non-explicit operator bools

[Marc-Aldorasi-Imprivata]

struct s
{
	operator bool() const { return false; }
};
std::ostream &boost_test_print_type(std::ostream &o, const s &) { return o << "s"; }

struct s2
{
	operator bool() const { return false; }
};
std::ostream &operator<<(std::ostream &o, const s2 &) { return o << "s2"; }

BOOST_AUTO_TEST_CASE(f)
{
	BOOST_TEST(s{});
	BOOST_TEST(s2{});
}

When printing out the failures in this test, the second check correctly uses operator<< to print out the value of s2, but the first check displays the value of s as 0. s should be printed out using boost_test_print_type instead.

Would you please check the branch topic/GH-158-boost_test_print_type-printing-on-single-value? It should solve this issue and the other you mentioned #158 .

[Marc-Aldorasi-Imprivata]

That fixes both issues, thanks.
