test bison-2.4.1b oke and feature req.

[tys lefering]

Hello,

Installed and tested Bison-2.4.1b without any problem on a
open suse Linux 11.2 64bits machine.

A feature request is to have a single line in the graph output
to indicate which tool it generated and the parser file name.

Now I edit the graphviz.c file with this:

void
start_graph (FILE *fout)
{
  fprintf (fout, "/* Generated with GNU Bison parser generator version %s
from '%s' */\n", VERSION, grammar_file);
  fputs ("digraph Automaton {\n", fout);
}

It is sometimes a problem a graph does not have such
information included when working with graphs from
different tools and sources.

Thanks.
