Licensing question: compatibility between Vim license and GPL

[Lifepillar]

Can code released under Vim license include third-party code released
under GPLv2 or GPLv3?

I have read that Vim license is "GPL-compatible", but it is not clear to
me which way such compatibility works.

Thanks for providing legal advice for free ;)

I am not a lawyer, nor do I play one on TV; but I believe that the
following (at the bottom of the ":help license" text) is relevant:

- According to Richard Stallman the Vim license is GNU GPL compatible.
A few minor changes have been made since he checked it, but that should not
make a difference.

- If you link Vim with a library that goes under the GNU GPL, this limits
further distribution to the GNU GPL. Also when you didn't actually change
anything in Vim.

- Once a change is included that goes under the GNU GPL, this forces all
further changes to also be made under the GNU GPL or a compatible license.

- If you distribute a modified version of Vim, you can include your name and
contact information with the "--with-modified-by" configure argument or the
MODIFIED_BY define.


Best regards,
Tony.

Thanks, that is also my understanding of the compatibility of the
licenses.

Thanks, that's useful.

This licensing stuff has higher complexity than the halting problem.
