bugs in the version-1.875e mentioned in the comp.compilers notice
1) vcg graph output has no ` title: "name" ' in the toplevel graph
2) use of keyword `expand' should be `stretch'
3) keyword `normal' for layoutalgorithm does only exist
   at commandline, not in the graph. in the vcg.c this
   keyword `normal' is mentioned, should not be there.
   in the graph output should be no line `layoutalgorithm:'
   to select the default layoutalgorithm.
4) a c-comment line in the vcg graph output with the bison
   version and input file would be nice, if possible with
   number of nodes/edges/backedges.
5) strtol() in handle_action_dollar() is missing check
   on complete number conversion. try ` $$=$1gnu ' no warning.
6) at around 32k %token statements strange things may happen.
