Expat,I think... I took the license file from github.
It does not have the paragraph, which is in the X11 license:
----
Except as contained in this notice, the name of the <copyright
holders> shall
not be used in advertising or otherwise to promote the sale, use
or other
dealings in this Software without prior written authorization from the
<copyright holders>.

I was thinking that the Expat MIT licence would be compatible with
Ken's GPLv2 farce analyser.
Point 2 of the GPLv2:
[...]
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
[...]
Clearly, if some GPLv2 Program is included in another work, that whole
work should be licensed under the terms of GPLv2.
In the reversed way, it is OK: some program licensed under the Expat
license, can be included into a work licensed under GPLv2. I think it's
what they mean with "compatible with GPL".
I think this is also the reason why GLPv2 is not even compatible with
GPLv3, unless the copyright notice tells that the work "is licensed
under GPLv2 or, at the user convenience any later version".
