* Revision 0.4 1991/11/19 12:34:41 dennisg
* bug in hash_delete(). It was using void* to obtain nodes to
* pass to hash_remove(). The value passed to hash_removed() is a
* entry from the node structure rather than the node itself. Using
* void* removed compiler checking.
* Modified to implement cache expansion.
*
* Revision 0.3 1991/11/07 23:23:40 dennisg
* implemented hash table expansion as suggested by rms.
