Thanks to feedback from Hans-Juergen Taenzer a mild memory leak in
hashlib has been exterminated.  The revised release is available
at:

  <http://cbfalconer.home.att.net/download/hashlib.zip>

in source form, under GNU licence.  The code is entirely portable
ISO standard C.  A test suite is included.

Hashlib is a generalized system for building, searching, deleting,
and generally manipulating data in hash tables.  The user supplies
several simple functions, including those to copy data objects,
create a hash function, on opening the hashtable.  The library
then controls all aspects, including the size of the hashtable. 
The library can manipulate multiple hash tables with the same code
and is re-entrant.  Examples show several usages, including how to
sort a snapshot of the table contents.

In general a hash table allows data storage and retrieval with
O(1) speed.  Performance can be heavily affected by the
suitability of the hash functions to the actual data, and thus
those functions are completely under the control of the user. 
Some userful hash functions for operating on strings are
available, together with links to functions for other forms of
data.
