     31  * Log: rf_dagffwr.h,v
     32  * Revision 1.6  1996/07/31 15:35:29  jimz
     33  * evenodd changes; bugfixes for double-degraded archs, generalize
     34  * some formerly PQ-only functions
     35  *
     36  * Revision 1.5  1996/07/22  19:52:16  jimz
     37  * switched node params to RF_DagParam_t, a union of
     38  * a 64-bit int and a void *, for better portability
     39  * attempted hpux port, but failed partway through for
     40  * lack of a single C compiler capable of compiling all
     41  * source files
     42  *
     43  * Revision 1.4  1996/06/10  22:25:28  wvcii
     44  * added write dags which do not have a commit node and are
     45  * used in forward and backward error recovery experiments.
     46  *
     47  * Revision 1.3  1996/05/24  22:17:04  jimz
     48  * continue code + namespace cleanup
     49  * typed a bunch of flags
     50  *
     51  * Revision 1.2  1996/05/23  21:46:35  jimz
     52  * checkpoint in code cleanup (release prep)
     53  * lots of types, function names have been fixed
     54  *
     55  * Revision 1.1  1996/05/03  19:20:18  wvcii
     56  * Initial revision
