Any  other  opinions on  this?   Last I  looked, yacc  did not insert
copyright notices in its output.  There is  no restriction  on use of
yacc output (I didn't sign anything to that effect, and I have yacc).
AT&T seems not to have chosen to restric use of their  parser.  Also,
I am  not a  yacc user,  but I  thought the  parser was  written in a
semi-bnf form by the yacc user, and yacc basically 'compiled' it to C
code.  If this is true, copyrighting yacc output is like copyrighting
a compiler's output.
