Description
The following test program:
#define BOOST_TEST_MODULE my_test
#include <boost/multiprecision/cpp_dec_float.hpp>
#define BOOST_TEST_MAIN
#include <boost/test/included/unit_test.hpp> // Note: header-only Boost.Test
#include <boost/test/floating_point_comparison.hpp>
BOOST_AUTO_TEST_CASE(my_test)
{
typedef boost::multiprecision::number<boost::multiprecision::cpp_dec_float<50>,
boost::multiprecision::et_off> mp_type;
const mp_type test_value = mp_type(12) / 7;
}
Fails to compile due to ambiguities between boost::enable_if and boost::unit_test::decorator::disable_if:

'd:\data\boost\trunk\boost\test\tree\decorator.hpp(184) : boost::unit_test::decorator::enable_if'
IMO Boost.Test should not pollute namespace boost with types of the same name as other types already there.
