Henry Spencer's license
by Petr Šabata
Dear legal,
While checking the contents of our `perl' package, I noticed the following:
(...)
/* NOTE: this is derived from Henry Spencer's regexp code, and should not
* confused with the original package (see point 3 below). Thanks, Henry!
*/
/* Additional note: this code is very heavily munged from Henry's version
* in places. In some spots I've traded clarity for efficiency, so don't
* blame Henry for some of the lack of readability.
*/
/* The names of the functions have been changed from regcomp and
* regexec to pregcomp and pregexec in order to avoid conflicts
* with the POSIX routines of the same names.
*/
(...)
* pregcomp and pregexec -- regsub and regerror are not used in perl
*

You can see the whole file here:

I looked but couldn't find any common name for this license
of Henry's. Is it on our list? Is it free? What name should
I use in the License tag?
Thank you,
Petr

Bison license exception
by Sandro Mani
Hi
While reviewing mingw-cfitsio, we encountered the situation of bison
parser sources [1][2] containing the following:
/* [... standard GPLv3+ header ...] */
/* As a special exception, you may create a larger work that contains
part or all of the Bison parser skeleton and distribute that work
under terms of your choice, so long as that work isn't itself a
parser generator using the skeleton or a modified version thereof
as a parser skeleton. Alternatively, if you modify or redistribute
the parser skeleton itself, you may (at your option) remove this
special exception, which will cause the skeleton and the resulting
Bison output files to be licensed under the GNU General Public
License without this special exception.
This special exception was added by the Free Software Foundation in
version 2.2 of Bison. */
cfitsio is licensed MIT. Is my understanding correct that this special
exception means that these files are also MIT licensed, being
distributed as part of cfitsio, and hence that the license field of the
package only needs to specify MIT?
Thanks
Sandro
