-// Deal with the differences between Microsoft and GNU implemenations

-// |base::hash_set|.
-//  eg:
-//   base::hash_map<int> my_map;
-//   base::hash_set<int> my_set;
-//
-// NOTE: It is an explicit non-goal of this class to provide a generic hash
-// function for pointers.  If you want to hash a pointers to a particular class,
-// please define the template specialization elsewhere (for example, in its
-// header file) and keep it specific to just pointers to that class.  This is
-// because identity hashes are not desirable for all types that might show up
-// in containers as pointers.
