The GPLWithACException is the same license that is used in m4/libtool.m4,
which we also ship:

# GNU Libtool is free software; you can redistribute it and/or
# modify it under the terms of the GNU General Public License as
# published by the Free Software Foundation; either version 2 of
# the License, or (at your option) any later version.

# As a special exception to the GNU General Public License,

# same distribution terms that you use for the rest of that program.

^ That's the exception.

I think it would be disingenuous to deny acx_pthread.m4 while still shipping
libtool.m4. Agree/disagree?

I'll see if I can take a crack at these. I've got some time to burn this
morning.

Most likely, I will send off a patch that fixes some of these work items.

BTW - I'm importing curl into git and will see about maintaining a regularly
updated mirror of it for everyone's use. That way, we can officially keep
using CVS until the power of distributed revision control seduces Daniel.
