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

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

Permission notice and disclaimer variant

I came across this license:

(So it's part of the autoconf archive.)
It's free and seems similar to HPND in construction, but I don't
recognize the wording. Has it already got a separate tag?
Thanks,
Florian
