The only reason why you might not be able to is that bison includes parts of itself in the generated source. I don't know about your version of bison, but in /usr/share/doc/bison.simple (Debian stable), there's the following: /* As a special exception, when this file is copied by Bison into a Bison output file, you may use that output file without restriction. This special exception was added by the Free Software Foundation in version 1.24 of Bison. */ So, it looks like you can do whatever you want with the generated code. > pete > > -- > Fingerprint: B9F1 6CF3 47C4 7CD8 D33E 70A9 A3B9 1945 67EA 951D > _______________________________________________ > vox-tech mailing list > [EMAIL PROTECTED] > http://lists.lugod.org/mailman/listinfo/vox-tech -- Samuel Merritt OpenPGP key is at http://meat.andcheese.org/~spam/spam_at_andcheese_dot_org.asc Information about PGP can be found at http://www.mindspring.com/~aegreene/pgp/
