+ * Revision 1.76  1997-10-27 14:33:04  adam
+ * Moved towards generic character mapping depending on "structure"
+ * field in abstract syntax file. Fixed a few memory leaks. Fixed
+ * bug with negative integers when doing searches with relational
+ * operators.
+ *
+ * Revision 1.75  1997/09/17 12:19:12  adam
+ * Zebra version corresponds to YAZ version 1.4.
+ * Changed Zebra server so that it doesn't depend on global common_resource.
+ *
+ * Revision 1.74  1997/09/09 13:38:06  adam
+ * Partial port to WIN95/NT.
+ *
+ * Revision 1.73  1997/09/04 13:57:20  adam
+ * New file extract/retrieve method tellf (added).
+ * Added O_BINARY for open calls.
+ *
+ * Revision 1.72  1997/07/15 16:32:29  adam
+ * Bug fix: Match handler didn't terminate the resulting string!
+ *
+ * Revision 1.71  1997/07/15 16:28:41  adam
  * Bug fix: storeData didn't work with files with multiple records.
  * Bug fix: fixed memory management with records; not really well
  *  thought through.
