#9267: flat_set and flat_map can't compile in VS2013 (variadic templates
activated)

I experimented the following:
In a fresh copy of boost trunk r86347, I made the following change:
1. go in boost/config/compiler/visualc.hpp
2. replace
{{{
// C++11 features supported by VC++ 12 (aka 2013).
//
#if _MSC_FULL_VER < 180020827

#endif
// variadic templates are supposed to be supported by VC++ 12
// but VC++ 12 RC variadic support is causing boost regression
// test failures for signals2 and several of its dependencies.

3. compile boost with vc12 - no error in the log, I checked this time but
I didn't try to run the tests;
Doing this fixes synchronized_value for me.
However, there is a strange compilation error I can't decipher with
flat_set and flat_map.
Compiling:
{{{
#include <boost/container/flat_map.hpp>
boost::container::flat_map<int, int> foo;
}}}
Generates the following error (please ignore the file names, I replaced
all the code by the code above):
{{{

With the following code:
{{{
#include <boost/container/flat_set.hpp>
boost::container::flat_set<int, int> foo;
}}}
I get these errors:

}}}
So I'm not sure if it's related to variadic templates activated or not but
it don't look so.
