Add licensing information to byacc's makefile

This makefile was included in the byacc distribution as Makefile.old
It was slightly updated to fit our needs.

Berkeley yacc itself is in the public domain, but SPDX/REUSE provides
no good way to represent this. In keeping with that spirit, I chose
CC0 as the license for my modifications, which SPDX can represent.

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

3. Distribution Obligations.
3.1. Availability of Source Code.
Any Covered Software that You distribute or otherwise make available in Executable
form must also be made available in Source Code form and that Source Code
form must be distributed only under the terms of this License. You must include
a copy of this License with every copy of the Source Code form of the Covered
Software You distribute or otherwise make available. You must inform recipients
of any such Covered Software in Executable form as to how they can obtain
such Covered Software in Source Code form in a reasonable manner on or through
a medium customarily used for software exchange.
3.2. Modifications.
The Modifications that You create or to which You contribute are governed
by the terms of this License. You represent that You believe Your Modifications
are Your original creation(s) and/or You have sufficient rights to grant the
rights conveyed by this License.
3.3. Required Notices.
You must include a notice in each of Your Modifications that identifies You
as the Contributor of the Modification. You may not remove or alter any copyright,
patent or trademark notices contained within the Covered Software, or any
notices of licensing or any descriptive text giving attribution to any Contributor
or the Initial Developer.
3.4. Application of Additional Terms.
You may not offer or impose any terms on any Covered Software in Source Code
form that alters or restricts the applicable version of this License or the
recipients rights hereunder. You may choose to offer, and to charge a fee
for, warranty, support, indemnity or liability obligations to one or more
recipients of Covered Software. However, you may do so only on Your own behalf,
and not on behalf of the Initial Developer or any Contributor. You must make
it absolutely clear that any such warranty, support, indemnity or liability
obligation is offered by You alone, and You hereby agree to indemnify the
Initial Developer and every Contributor for any liability incurred by the
Initial Developer or such Contributor as a result of warranty, support, indemnity
or liability terms You offer.
3.5. Distribution of Executable Versions.
You may distribute the Executable form of the Covered Software under the terms
of this License or under the terms of a license of Your choice, which may
contain terms different from this License, provided that You are in compliance
with the terms of this License and that the license for the Executable form
does not attempt to limit or alter the recipients rights in the Source Code
form from the rights set forth in this License. If You distribute the Covered
Software in Executable form under a different license, You must make it absolutely
clear that any terms which differ from this License are offered by You alone,
not by the Initial Developer or Contributor. You hereby agree to indemnify
the Initial Developer and every Contributor for any liability incurred by
the Initial Developer or such Contributor as a result of any such terms You
offer.
3.6. Larger Works.
You may create a Larger Work by combining Covered Software with other code
not governed by the terms of this License and distribute the Larger Work as
a single product. In such a case, You must make sure the requirements of this
License are fulfilled for the Covered Software.
4. Versions of the License.
4.1. New Versions.
Sun Microsystems, Inc. is the initial license steward and may publish revised
and/or new versions of this License from time to time. Each version will be
given a distinguishing version number. Except as provided in Section 4.3,
no one other than the license steward has the right to modify this License.
4.2. Effect of New Versions.
You may always continue to use, distribute or otherwise make the Covered Software
available under the terms of the version of the License under which You originally
received the Covered Software. If the Initial Developer includes a notice
in the Original Software prohibiting it from being distributed or otherwise
made available under any subsequent version of the License, You must distribute
and make the Covered Software available under the terms of the version of
the License under which You originally received the Covered Software. Otherwise,
You may also choose to use, distribute or otherwise make the Covered Software
available under the terms of any subsequent version of the License published
by the license steward.
4.3. Modified Versions.
When You are an Initial Developer and You want to create a new license for
Your Original Software, You may create and use a modified version of this
License if You: (a) rename the license and remove any references to the name
of the license steward (except to note that the license differs from this
License); and (b) otherwise make it clear that the license contains terms
which differ from this License.
5. DISCLAIMER OF WARRANTY.
COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN “AS IS” BASIS, WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION,
WARRANTIES THAT THE COVERED SOFTWARE IS FREE OF DEFECTS, MERCHANTABLE, FIT
FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY
AND PERFORMANCE OF THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY COVERED SOFTWARE
PROVE DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER
CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION.
THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE.
NO USE OF ANY COVERED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
6. TERMINATION.
6.1. This License and the rights granted hereunder will terminate automatically
if You fail to comply with terms herein and fail to cure such breach within
30 days of becoming aware of the breach. Provisions which, by their nature,
must remain in effect beyond the termination of this License shall survive.
6.2. If You assert a patent infringement claim (excluding declaratory judgment
actions) against Initial Developer or a Contributor (the Initial Developer
or Contributor against whom You assert such claim is referred to as “Participant”)
alleging that the Participant Software (meaning the Contributor Version where
the Participant is a Contributor or the Original Software where the Participant
is the Initial Developer) directly or indirectly infringes any patent, then
any and all rights granted directly or indirectly to You by such Participant,
the Initial Developer (if the Initial Developer is not the Participant) and
all Contributors under Sections 2.1 and/or 2.2 of this License shall, upon
60 days notice from Participant terminate prospectively and automatically
at the expiration of such 60 day notice period, unless if within such 60 day
period You withdraw Your claim with respect to the Participant Software against
such Participant either unilaterally or pursuant to a written agreement with
Participant.
6.3. In the event of termination under Sections 6.1 or 6.2 above, all end
user licenses that have been validly granted by You or any distributor hereunder
prior to termination (excluding licenses granted to You by any distributor)
shall survive termination.
7. LIMITATION OF LIABILITY.
UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING
NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL DEVELOPER, ANY
OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED SOFTWARE, OR ANY SUPPLIER
OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL,
INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION,
DAMAGES FOR LOST PROFITS, LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE
OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF
SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS
LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL
INJURY RESULTING FROM SUCH PARTYS NEGLIGENCE TO THE EXTENT APPLICABLE LAW
PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION
MAY NOT APPLY TO YOU.
8. U.S. GOVERNMENT END USERS.
The Covered Software is a “commercial item,” as that term is defined in 48
C.F.R. 2.101 (Oct. 1995), consisting of “commercial computer software” (as
that term is defined at 48 C.F.R. § 252.227-7014(a)(1)) and “commercial computer
software documentation” as such terms are used in 48 C.F.R. 12.212 (Sept.
1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
(June 1995), all U.S. Government End Users acquire Covered Software with only
those rights set forth herein. This U.S. Government Rights clause is in lieu
of, and supersedes, any other FAR, DFAR, or other clause or provision that
addresses Government rights in computer software under this License.
9. MISCELLANEOUS.
This License represents the complete agreement concerning subject matter hereof.
If any provision of this License is held to be unenforceable, such provision
shall be reformed only to the extent necessary to make it enforceable. This
License shall be governed by the law of the jurisdiction specified in a notice
contained within the Original Software (except to the extent applicable law,
if any, provides otherwise), excluding such jurisdictions conflict-of-law
provisions. Any litigation relating to this License shall be subject to the
jurisdiction of the courts located in the jurisdiction and venue specified
in a notice contained within the Original Software, with the losing party
responsible for costs, including, without limitation, court costs and reasonable
attorneys fees and expenses. The application of the United Nations Convention
on Contracts for the International Sale of Goods is expressly excluded. Any
law or regulation which provides that the language of a contract shall be
construed against the drafter shall not apply to this License. You agree that
You alone are responsible for compliance with the United States export administration
regulations (and the export control laws and regulation of any other countries)
when You use, distribute or otherwise make available any Covered Software.
10. RESPONSIBILITY FOR CLAIMS.
As between Initial Developer and the Contributors, each party is responsible
for claims and damages arising, directly or indirectly, out of its utilization
of rights under this License and You agree to work with Initial Developer
and Contributors to distribute such responsibility on an equitable basis.
Nothing herein is intended or shall be deemed to constitute any admission
of liability.
