Yes config_info is just a report, config_test is the consolidated test 
program for Boost.Config.

Turning BOOST_HAS_NVRO on for VC8 causes the test program to fail, unless 
optimisations are turned on, in which case it is indeed supported.

So I suggest we add:

#if (_MSC_VER >= 1400) && !defined(_DEBUG)
# define BOOST_HAS_NRVO
#endif

to visualc.hpp, note that _DEBUG isn't really the right macro to use here, 
but it's as close an approximation as we can get.

Thoughts?

John.
