No, this doesn't look like the GPL.

This one is OK.

I decided not to put a copyright notice in every source file because I
read somewhere (I don't remember where) that a COPYING file is enough
for the whole package. Anyway, I will put the notice for the next
release, if this is required by Debian.

Both yes and no:
Yes, I intentionally switched to GPLv3 (out of pure zealotry :-).
No, autoconf-orb's license doesn't have to be the same as autoconf's.
autoconf-orb is not derived from autoconf. The relation between the two
is like a C program file and a header from glibc. I could have chosen
any license for autoconf-orb.
If you feel that I 'm wrong here, please let me know why. I can easily
revert back to GPLv2.

Since the main part of automake-idl is a patch for automake.in (I can't
change the license here), and the latter already has a copyright notice,
I decided not to copyright the rest of the files differently.
About the upstream inclusion - not that I don't want it, but I doubt
that it would ever be accepted (autoconf-orb has become quite a beast,
and automake-idl doesn't make sense without it; besides, CORBA is not
very popular these days), so I've decided not to try it.

Yes, I am the only author.

In short:
1. I will put the copyright notices in autoconf-orb's files in the next
release.
2. If you know any reason for autoconf-orb to be switched back to GPLv2
then let me know.
3. Anything else?
