container std_fwd.hpp neglects custom std namespaces

[dmorilha@…]

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 }
#endif

Current develop and master branches contain code that tries to detect GCC std namespace versioning macro:

Would this fix your problem?

It compiles all right, so I guess it fixes the problem.

Thanks for the report. Fixed in release branch for boost 1.58.
