gplv3 files and updates

[Karl Berry]

I am not sure how best to put GPLv3 and LGPLv3 into gnulib.
I think that when projects update to GPLv3, the "COPYING" file should be
GPLv3.  But of course until the update, COPYING remains GPLv2.

Maybe we should have doc/COPYINGv2 and doc/COPYINGv3 (ditto
COPYING.LESSER) in gnulib, with no doc/COPYING at all, so the choice is
explicit?  Other ideas?


On the more important topic of actually updating gnulib: rms said that
libc should not be updated yet.  He also said gnulib should not be
updated, but I think he meant "libc" when he wrote "gnulib", not being
immediately aware that they're two different things.  I thought I would
ask him about it a little later.

BTW, gnulib still takes a couple of files directly from libc (strtoll.c
and strtoul.c), but I believe all the others have diverged by now.

Thanks,
Karl
