#10930: container std_fwd.hpp neglects custom std namespaces
-------------------------+-------------------------------------------------
 Reporter:  dmorilha@…   |       Type:  Bugs
   Status:  new          |  Milestone:  To Be Determined
Component:  None         |    Version:  Boost 1.57.0
 Severity:  Problem      |   Keywords:  std namespace libstdc++
                         |  BOOST_CONTAINER_STD_NS_BEG
-------------------------+-------------------------------------------------
 I've a special gcc with versioned libstdc++ std namespace (compiled with
 --enable-symvers=gnu-versioned-namespace).

 The file container/detail/std_fwd.hpp fails to detect that and assumes std
 namespace to be "std" [1]. It generates problems during compilation.

 My current workaround is to define the header macro in the compiler's
 argument list and remove this file content out.

 A different fix - possibly detecting the proper std namespace - would be
 ideal here.

 #else
    #define BOOST_CONTAINER_STD_NS_BEG namespace std{
    #define BOOST_CONTAINER_STD_NS_END }
