 Thanks again for the new BOOST_TEST() tool, which looks very useful.

 Unfortunately, I'm seeing strange behaviour from the following code under
 `g++ -std=c++11` or `clang++ -std=c++11 -stdlib=libc++` :

 {{{#!cpp
 #define BOOST_TEST_MODULE zero_mod

 #include <boost/test/included/unit_test.hpp>

 BOOST_AUTO_TEST_CASE( zero ) {
         BOOST_TEST( 0.0 == 0.0 );
 }
 }}}

 If I compile with `-std=c++11`, then the test fails:

 {{{
 error: in "zero": check 0.0 == 0.0 has failed [0 != 0]. Absolute value
 exceeds tolerance [|0| > 0]
 }}}

 ...but I compile without any `-std=[...]` option, then the test passes.
