Ah, yeah, excuse me gentlemen, I believe you're on the wrong list.

  Nope, you are.  Cygwin-whine-complain-moan-grumble is over that-a-way ---->

  However, while we're here, the answers to your questions are:

  LicensOR is allowed to distribute licensOR's own copyrighted software any
damn way LicensOR wishes, since GPL obligations apply to licensEE.  Guess
RedHat has decided not to sue itself gratuitously.

  Yes it is.

  Guess what's in the tarball, Gary!  Yes, you thought it was just the
executable, only zipped up to make it three times bigger than the raw binary,
but no!  It's the source!

So, since LicensOR is me (and several dozen other people, and Red Hat), none
of us have to obey either the spirit or letter of the GPL?  Or are we
supposed to sue ourselves round-robin style?  You've lost me Dave.  Perhaps
a quick grep through the source for copyright notices will clarify things.

Oh, and watch the potty mouth.

What tarball?  When I posted the message to which you refer, there was no
tarball there, as you are of course now all too aware.  Luckily, I was able
to bring this state of affairs to the attention of the proper authorities
and get it corrected before any LicensORs or LicensEEs were harmed.  Said it
before, say it again: measure twice, cut once.

No, I thought it wasn't there.  Which it wasn't.

And now it's actually there, thanks to my sharp eye and Brian's mad ftp
skillz.  You're more than welcome Korns.  If there's anything more I can do
to help, just give me a shout.
