- * Revision 1.15 1996-03-20 09:35:18 adam
+ * 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.
