First always keep the cc to the Help-Bison list so that others may help.
Then second, it is best to read the GNU license in the parser output,
as suggested by another poster. There is a general principle of
copyright treaty and copyright law, though, that the work you are
doing is always copyrighted to you, and that copyright ownership
cannot be abrogated except by yourself. A GNU license can restrict
the uses of the GNU human copyrighted work, but it does not apply to
the processing any computer program does though, since no human is
involved creatively in that. So Bison processing itself cannot
abrogate your copyrights. You can put your copyrights as notices in
the .y file if you so want, because (I think) it is just copied over
verbatim, though material nowadays automatically become copyrighted
regardless of such notices. Also see:

Dear Mr. Aberg,
Thank you very much for your reply. I would like to know this:
1. We plan to use Bison to generate code for us for a commercial
application. Now, should we distribute the sources of our commercial
application to the outside world because it used Bison to generate
code
?
2. If yes, then what is the alternative, as we would want our source
code to be our private property.
Thanks and Regards
Anup

let me know if I can use it without any problem. If not, could you
please let me know the licensing issues w.r.t Bison.
I think that the state of the matter (of the most recent Bison
versions), is that you can freely use the C-parser in a commercial
application, the same way that you can use GCC libraries and the
like. Check the notice in the parser sources that Bison writes. The
copyrighting of this parser only applies to the parts that derives
from the skeleton file. The other parts deriving from the grammar you
write is copyrighted to you. As for the GLR and C++ parsers, they may
have different copyrighting notices, but may be synced in the future
as to become what the C-parser has today.
