According to the 1995 edition of lex & yacc 'Parsers generated with bison 
are subject to the GNU "copyleft" software license ... If you plan to use 
bison to develop a program distributed to tohers, be sure to check the file 
COPYING included in the bison distribution to see if you agree to the 
terms.'

Unless the license has changed in the last six years, anyway.
