[mod.compilers] Who owns yacc parsers

johnl@ima.UUCP (01/17/86)

Since the topic of who owns yacc parsers has come up again, I asked a
friend who negotiates Unix licensing agreements for a Unix vendor.  She
reports that the System V rel 2.0 license specifically says that it is ok
to include /usr/lib/yaccpar in applications without payment of a
sublicensing fee.

I gather that System V 2.0 agreements are all that AT&T is selling these days,
since they grandfather all of the previous versions, and the upgrade from
System III or System V is cheap.
