Please note that asking upstream to switch from GPL-2 to GPL-2+ is
not the only way out from this license incompatibility issue.
See my [message] to debian-legal for more information.

Some of these alternative strategies have already been mentioned in the
original bug report...

If you are going for option b (ask the copyright holders to re-license
the program from GPL-2 to GPL-2+), then the best possible outcome would
be to have them add the appropriate boilerplate to all the files.

Failing that, a centralized LICENSE or README file placed by the
copyright holders could suffice (or even a documented e-mail exchange
with all the copyright holders, as a last resort).

I hope this helps.
Thanks for taking care of this!

 There's not a second to spare! To the laboratory!
