+ * Revision 1.22  1999-02-02 14:50:23  adam
+ * Updated WIN32 code specific sections. Changed header.
+ *
+ * Revision 1.21  1998/06/24 12:16:12  adam
+ * Support for relations on text operands. Open range support in
+ * DFA module (i.e. [-j], [g-]).
+ *
+ * Revision 1.20  1997/10/27 14:33:03  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 1.19  1997/09/18 08:59:18  adam
+ * Extra generic handle for the character mapping routines.
+ *
+ * Revision 1.18  1997/09/05 15:29:58  adam
+ * Changed prototype for chr_map_input - added const.
+ * Added support for C++, headers uses extern "C" for public definitions.
+ *
+ * Revision 1.17  1996/06/04 10:20:06  adam
+ * Added support for character mapping.
+ *
+ * Revision 1.16  1996/05/24  14:46:04  adam
+ * Added dict_grep_cmap function to define user-mapping in grep lookups.
+ *
+ * Revision 1.15  1996/03/20  09:35:18  adam
  * Function dict_lookup_grep got extra parameter, init_pos, which marks
  * from which position in pattern approximate pattern matching should occur.
