// This section is to sort out whether hash types or unordered types
// are available. This depends on whether stdlib or libc++ is being used
// and also whether C++11 or C++03 is being used.
//////////////////////////////////////////////////////////////////////////
// The idea is to set up the configuration without including the actual
// headers unless that is unavoidable.
//
// The client code should contain the following to include headers
//
// #ifdef BOOST_PHOENIX_HAS_HASH
// #include BOOST_PHOENIX_HASH_SET_HEADER
// #include BOOST_PHOENIX_HASH_MAP_HEADER
// #endif
//
// #ifdef BOOST_PHOENIX_HAS_UNORDERED_SET_AND_MAP
// #include BOOST_PHOENIX_UNORDERED_SET_HEADER
// #include BOOST_PHOENIX_UNORDERED_MAP_HEADER
// #endif
//
// The client code can then chose the implementation provided.
// See the example in test/stl/querying_find2.cpp

// There is no specific thing in Boost Config for libc++
