This is a good solution. Compiled and tested new bison and all oke.

Now it is possible to find what a graph is about if needed
with the parser name in the graph and the tool version.

Also it will appear on the internet with 'google bison filetype:dot'
to find bison generated dot files around on webservers.

The tool version info is also needed in gcc graph output
because current gcc generates sometimes incorrect graph output
and when this gets fixed it is needed to know from the graph
data which tool generated it.

ps. Wisent is an Elisp implementation of Bison. The Elisp code
is a port of the C code of GNU Bison 1.28 & 1.31.
The wisent has also a simple dot graph parser in :
CEDET file cogre/wisent-dot.wy, and cogre/wisent-dot.el

Thanks for this nice patch.
