// Inclusion of this file is DEPRECATED. This is the original HP
// default allocator. It is provided only for backward compatibility.
//
// DO NOT USE THIS FILE unless you have an old container implementation

// uses a different allocator interface. SGI-style allocators are not
// parametrized with respect to the object type; they traffic in void *
// pointers. This file is not included by any other SGI STL header.
