I found some recent change in Boost.Concept will cause a compilation error,
which will cause fails in several libs, including Log, Graph, etc. I'm
not sure if
it is what being discussed here.

A small script code to demo it:

// Begin test_code.cpp
#include <boost/concept_check.hpp>
#include <boost/concept/detail/concept_def.hpp>

namespace boost
   BOOST_concept(ReadableIterator, (Iterator))
     : boost::Assignable<Iterator>
     , boost::CopyConstructible<Iterator>

int main(int argc, char* argv[])
   return 0;
// End test_code.cpp

Supposed boost trunk is in c:\boost, then open a VS2012/VS2013RC command
line and run:
cl /EHsc -I c:\boost test_code.cpp

will get:
test_code.cpp(7) : error C2065: 'ReadableIterator' : undeclared identifier

The similar error will happen while compiling Log, Graph, etc.
