 Compiling the following code with GCC 5.3.0 (C++11/14) I get an error on
 the second but not on the first test case.

 {{{#!cpp
 #include <boost/test/included/unit_test.hpp>
 #include <boost/test/data/test_case.hpp>

 using boost::unit_test::data::xrange;

 BOOST_DATA_TEST_CASE(Test_3D_grid,
                      xrange(2) * xrange(2) * xrange(2), a, b, c) {}

 BOOST_DATA_TEST_CASE(Test_4D_grid,
                      xrange(2) * xrange(2) * xrange(2) * xrange(2), a, b,
 c,
                      d) {}
 }}}

 The error reads

 {{{
 /usr/include/boost/test/data/test_case.hpp:107:5: error: no matching
 function for call to 'bind(<unresolved overloaded function type>, const
 std::tuple<int, int, int>&, const int&)'
      BOOST_PP_REPEAT_FROM_TO(1, 4, TC_MAKE, _)
 }}}

 Are four and more parameters not supported for data test cases?

 The documentation says

 > BOOST_DATA_TEST_CASE(test_case_name, dataset, var1, ..., varN) { /*
 datasets of arity N */ }

 without giving any limits on N.
