I think it is:
http://www.gnu.org/licenses/license-list.html#GPLIncompatibleLicenses
"Original BSD license
(Note: on the preceding link, the original BSD license is listed in the UCB/LBL
section. This license is also sometimes called the “4-clause BSD license”.)
This is a simple, permissive non-copyleft free software license with a serious
flaw: the “obnoxious BSD advertising clause”. The flaw is not fatal; that is,
it does not render the software non-free. But it does cause practical problems,
including incompatibility with the GNU GPL."
which links to
http://www.gnu.org/philosophy/bsd.html
which says:
There are many variants of simple non-copyleft free software licenses,
such as the Expat license, FreeBSD license, X10 license, the X11 license, and
the two BSD (Berkeley Software Distribution) licenses. Most of them are
equivalent except for details of wording, but the license used for BSD until
1999 had a special problem: the “obnoxious BSD advertising clause”. It said
that every advertisement mentioning the software must include a particular
sentence:
3. All advertising materials mentioning features or use of this software
must display the following acknowledgement:
This product includes software developed by the University of
California, Berkeley and its contributors.
Initially the obnoxious BSD advertising clause was used only in the
Berkeley Software Distribution. That did not cause any particular problem,
because including one sentence in an ad is not a great practical difficulty.
If other developers who used BSD-like licenses had copied the BSD
advertising clause verbatim—including the sentence that refers to the
University of California—then they would not have made the problem any bigger.
But, as you might expect, other developers did not copy the clause
verbatim. They changed it, replacing “University of California” with their own
institution or their own names. The result is a plethora of licenses, requiring
a plethora of different sentences.
When people put many such programs together in an operating system, the
result is a serious problem. Imagine if a software system required 75 different
sentences, each one naming a different author or group of authors. To advertise
that, you would need a full-page ad.
This might seem like extrapolation ad absurdum, but it is actual fact.
In a 1997 version of NetBSD, I counted 75 of these sentences. (Fortunately
NetBSD has decided to stop adding them, and to remove those it could.)
I don't know what copyright this Web page:
http://tommysprinkle.com/mvs/P3270/sbaxlate.htm
and the table page going along with it:
http://tommysprinkle.com/mvs/P3270/bufaddr.htm
has, but that might be the same operation (if TN3270 just sends a 3270 data
stream over the wire). If somebody wants to write up some code that takes two
bytes and turns them into a row and column address, reversing the
transformation described on that page - *without* looking at the TN3270
dissector - and send them to me or the list for inclusion in that routine, that
might help. (I've already seen the offending code, so I'm not sure I should
write any replacement.)
