It cut's both ways: there are compilers that don't set __cplusplus to 
the 2011 value but which will none the less compile your code, others 
which do, but which will not compile your code.  So I would be inclined 
to use the actual config check macros you use in your code in the 
Boost.Config build checks.  Also add some #ifdef's to the test case 
source so it becomes a "do nothing" test on compilers that don't support 
the features you're using.

HTH, John.
