[boost] [config] Dinkumware 4.0.2 has hash containers

Dinkumware used in Borland BDS 2006 contains hash containers but Boost.Config does not know about it. dinkumware.hpp could be updated: #if (defined _CPPLIB_VER) && (_CPPLIB_VER >= 402) # ifdef __BORLANDC__ // BDS 2006 STL has hash containers # define BOOST_HAS_HASH # endif #endif Possibly this is true for other systems than BCB but I do not have access to these. /Pavel
