hi, very easy ported the vcg graph output drivers from bison-2.3a into the bison-2.4.1 version. now there is a choice of graph output to use.
when using 'bison -g parser.y' then it generates both dot and vcg graph output and when a filename is specified using 'bison --graph=filename parser.y' then it generates only dot output. made a bison-2.4.1-vcg.tar.gz if someone is interested. can also generate the diffs. best regards, tys lefering.
