The documentation for BOOST_HAS_HASH says the following:

     Description: The C++ implementation provides the (SGI) hash_set or hash_map
classes.

Since the Dinkumware implementation is not compatible with the SGI interface,
the failure to define BOOST_HAS_HASH would seem to be correct.

It's a bit tricky to write code that works with both implementations,
particularly since the templates have different numbers of parameters.
