About four years ago AT&T explicitly said that the output of Yacc and Lex
were not subject to license conditions.  They also lifted the requirement
on other stuff that used things from /usr/lib, but I don't remember the
specifics; contact 1-800-828-UNIX for details.

DEC probably has the same licensing arrangement, but I would check with
them before posting.  In particular, make sure you don't put out something
with a DEC copyright in it (/usr/lib/ncform, or /usr/lib/yaccpar).  DEC
got in trouble once becuase someone repackaged ATT Yacc and sent it out
through DECUS.
