+ *
+ * 2.0 eay - Fixed a bug that occurred when using lh_delete
+ *           from inside lh_doall().  As entries were deleted,
+ *           the 'table' was 'contract()ed', making some entries
+ *           jump from the end of the table to the start, there by
+ *           skipping the lh_doall() processing. eay - 4/12/95
+ *
+ * 1.9 eay - Fixed a memory leak in lh_free, the LHASH_NODEs
+ *           were not being free()ed. 21/11/95
+ *
+ * 1.8 eay - Put the stats routines into a separate file, lh_stats.c
+ *           19/09/95
+ *
+ * 1.7 eay - Removed the fputs() for realloc failures - the code
+ *           should silently tolerate them.  I have also fixed things
+ *           lint complained about 04/05/95
+ *
+ * 1.6 eay - Fixed an invalid pointers in contract/expand 27/07/92
+ *
+ * 1.5 eay - Fixed a misuse of realloc in expand 02/03/1992
+ *
+ * 1.4 eay - Fixed lh_doall so the function can call lh_delete 28/05/91
+ *
+ * 1.3 eay - Fixed a few lint problems 19/3/1991
+ *
+ * 1.2 eay - Fixed lh_doall problem 13/3/1991
+ *
+ * 1.1 eay - Added lh_doall
+ *
+ * 1.0 eay - First version
