- Subject: Libiberty license roundup (questions/potential problems)
Looking at libiberty, it seems to be under a mass of different licences.
There are several problems here. The first are the (non-autogenerated) files
with no explicit copyright notice or licence. I would assume that they were
under the terms of the "rest of libiberty", except that it's not clear
what that is.
The second are the two files with copyright and no license listed.
The third are the BSD files with no explicit modification permission.
The fourth are the various files which aren't sure what they're part of; I'd
like permission to just fix those all to claim to be part of libiberty, unless
there's some reason not to.
The fifth is the question of why some are LGPL, some are GPL, some are GPL
with linking exception, and one is LGPL with linking exception. Effectively
the library as a whole is under GPL in general, it would seem; what purpose
do the other licenses serve?
