Currently, value_init_workaround_test.cpp fails on both msvc-14.0 and 14.1, 
because in:

#ifdef BOOST_DETAIL_VALUE_INIT_WORKAROUND_SUGGESTED
  // One or more failures are expected.
  return num_failures > 0 ? EXIT_SUCCESS : EXIT_FAILURE;
#else
  // No failures are expected.
  return num_failures == 0 ? EXIT_SUCCESS : EXIT_FAILURE;
#endif

failures are supposedly expected 
(BOOST_DETAIL_VALUE_INIT_WORKAROUND_SUGGESTED is defined), but there are 
none.

BOOST_DETAIL_VALUE_INIT_WORKAROUND_SUGGESTED is controlled by 
BOOST_NO_COMPLETE_VALUE_INITIALIZATION, which is defined on 14.0/14.1.

The Config macro is defined because - presumably - msvc 14.0/14.1 fail the 
Config test for value initialization, boost_no_com_value_init.ipp.

But this test is much more comprehensive than the value_init one. So to fix 
the value_init_workaround_test.cpp failure, we need to at minimum move one 
failing test case from the Config test to the value_init one.
