#7707: clang + C++11 + libstdc++ compile errors
------------------------------+---------------------------------------------
 Reporter:  viboes            |       Owner:  pdimov   
     Type:  Bugs              |      Status:  new      
Milestone:  To Be Determined  |   Component:  smart_ptr
  Version:  Boost 1.52.0      |    Severity:  Problem  
 Keywords:                    |  
------------------------------+---------------------------------------------
 There are a lot of errors when compiling with clang on c++11 mode and
 linking with the default library libstdc++. The erros come from the fact
 that the code is expecting the standard library to provide some c++11
 features which are missing, as std::forward.
