 * Compatibility header file for STL extension "hash_map".  Any other
 * source file that needs to use hash_map should include this instead.
 * 
 * If hash_map is not defined in namespace std, we bring it in there.
 * It turns out that different versions of gcc use different
 * namespaces for STL extensions (std, __gnu_cxx, and God knows
 * what'll be next).
 * 
 * This header assumes that only one of HAVE_*_HASH_MAP symbols is
 * defined.
