5197,Forward declarations from std:: not allowed in libc++,Chris Jefferson,Ion Gaztañaga,"interprocess uses the forward declarations from std::

template <class T>
class allocator;

template <class T>
struct less;

template <class T1, class T2>
struct pair;

template <class CharType> 
struct char_traits;

libc++ does not support these. There are various possible fixes. These forward declarations could just be replaced by the headers:

#include <utility>
#include <memory>
#include <functional>
#include <iosfwd>

or we could introduce a macro ( BOOST_ALLOWS_FWD_STD_DECLARATIONS ), or create a detail header for forward declarations.

I am happy to implement any of these, I am interested what the developers of interprocess think.",Bugs,closed,To Be Determined,interprocess,Boost 1.45.0,Problem,fixed,,
