Re: [boost] [config] Macro for null pointer

First go at it:

/*** BEGIN NULLPTR DEFINITION ***/

#include <boost/config.hpp>

#ifndef BOOST_NO_NULLPTR

#include <cstddef>

namespace boost {

typedef std::nullptr_t nullptr_t;

} // namespace boost

#else // #ifndef BOOST_NO_NULLPTR

[...]

using boost::nullptr;

One thing I wonder about is if this using declaration is The Right Thing To Do. An alternative is to provide a macro to bring the nullptr identifier into the current scope (and which does nothing in C++11).

#endif // #ifndef BOOST_NO_NULLPTR
