[comp.os.minix] yacc lex

dono@killer.UUCP (09/24/87)

I seem to have inadvertantly opened a real can of worms; after I had posted the
yacc code to this newsgroup I received a letter from decus, and this morning
9-24-87 I received another letter from att. They both follow; I am really  
confused by the whole mess and if I could pull the postings from the net I 
would. Sorry for taking up the net with this garbage but I feel like trying
to straighten it up.

Letters to me:

I strongly suspect that it is proprietary to
AT&T.  Before you post it, I would recommend your talking with the
AT&T lawyers to make sure you aren't inadvertantly publishing something
you have no right to.

As far as I know, there is no public-domain yacc available from Decus.
If you know of a distribution, I would appreciate knowing it so the
Decus library can check it out.  A version of Lex written by Charles
Forsythe was distributed with Decus C (11-SP-18) for which I am responsible.
I do have permission from Charles to include Lex on Decus C distributions,
but I don't know whether Austin Code Works (or anyone else) has permission
to further distribute it.  As distributed by Decus, Lex bears Charles'
copyright notice.

Subject: 'public domain' yacc/lex

1. Decus no longer distributes yacc/lex code on their tapes.
It is AT&T Proprietary [and Copyrighted] code. We can get into
a long discussion about it but I'd rather not. It was proprietary
before code could be copyrighted, and only distributed to UNIX
license holders. I do not know how it wound up on a DECUS tape.
Since the law has changed, it has been copyrighted. In any case,
even though copies [without copyright notice] abound, it still
belongs to AT&T.

2. The AT&T Legal dept has been in touch with Austin Code Works
[I do not know the status or details of the communication]. I believe
they were asked to stop distributing AT&T code or to pay the
appropiate royalties.

3. I posted a notice in comp.sources.d asking folks to check
with the proper AT&T legal dept [they have an 800 number]
I will attempt to retrieve a copy of the notice and the phone
number so that you may verify the legal status of the code.
Please refrain from posting code until you have checked first.
