+  7.8.02 Goetz
+  Implemented scc algorithm.  Added datastructure to mark
+  backedges (ana/backedge.h) and to represent loops
+  (ana/irloop.h).  The scc algorithm (ana/irscc.c) builds
+  both datastructures.
+  The algorithm does not yet work properly for interprocedural
+  graphs.  Finds more loops than only recursions.
+
+  Improved place_code: now moves nodes out of loops.
+  Fixed bug in iropt.c:  wrong parameter in debug info: iropt_dbg.c
+  Now flag set_opt_control_flow can be set to 1 again.
