- * Revision 1.1 1995-02-02 16:21:54 quinn
+ * Revision 1.24 1999-04-20 09:56:48 adam
+ * Added 'name' paramter to encoder/decoder routines (typedef Odr_fun).
+ * Modified all encoders/decoders to reflect this change.
+ *
+ * Revision 1.23 1998/03/20 14:45:01 adam
+ * Implemented odr_enum and odr_set_of.
+ *
+ * Revision 1.22 1998/02/11 11:53:34 adam
+ * Changed code so that it compiles as C++.
+ *
+ * Revision 1.21 1997/11/24 11:33:56 adam
+ * Using function odr_nullval() instead of global ODR_NULLVAL when
+ * appropriate.
+ *
+ * Revision 1.20 1997/09/29 07:17:31 adam
+ * Added typecast to avoid warnings on MSVC.
+ *
+ * Revision 1.19 1997/06/23 10:31:11 adam
+ * Added RVDM's SEQUENCE OF patch again!
+ *
+ * Revision 1.18 1997/05/14 06:53:58 adam
+ * C++ support.
+ *
+ * Revision 1.17 1997/05/05 11:21:09 adam
+ * In handling of SEQUENCE OF: Counter set to zero when SEQUENCE
+ * OF isn't there at all.
+ *
+ * Revision 1.16 1995/09/29 17:12:26 quinn
+ * Smallish
+ *
+ * Revision 1.15 1995/09/27 15:03:00 quinn
+ * Modified function heads & prototypes.
+ *
+ * Revision 1.14 1995/08/15 11:16:39 quinn
+ * Fixed pretty-printers.
+ *
+ * Revision 1.13 1995/05/22 14:56:57 quinn
+ * Fixed problem in decoding empty sequence.
+ *
+ * Revision 1.12 1995/05/18 13:06:32 quinn
+ * Smallish.
+ *
+ * Revision 1.11 1995/05/17 08:41:54 quinn
+ * Small, hopefully insignificant change.
+ *
+ * Revision 1.10 1995/05/16 08:50:59 quinn
+ * License, documentation, and memory fixes
+ *
+ * Revision 1.9 1995/03/17 10:17:57 quinn
+ * Added memory management.
+ *
+ * Revision 1.8 1995/03/15 11:18:05 quinn
+ * Fixed serious bug in odr_cons
+ *
+ * Revision 1.7 1995/03/08 12:12:30 quinn
+ * Added better error checking.
+ *
+ * Revision 1.6 1995/02/10 15:55:29 quinn
+ * Bug fixes, mostly.
+ *
+ * Revision 1.5 1995/02/09 15:51:49 quinn
+ * Works better now.
+ *
+ * Revision 1.4 1995/02/07 17:53:00 quinn
