In order for me to *use* autoconf in our build system, I need to *use* the version that we build/ship.

We are distributing autoconf.  Apple's autoconf is stuck at 2.61 and not able to go up.  When building mesa in our build system, we use our autoconf.  Furthermore, as stated before by Alan, I'm restricted from *using* GPLv3 software.  I direct you to public statements from Apple by people who are paid to make public statements.  I just do what the lawyers say and no amount of arguing about the license will change it.

With my personal hat on, I use GPLv3 software, I contribute patches to GPLv3 projects, but I will never release software as GPLv3 because of the headaches it causes.

It applies to us in what version of autoconf we can redistribute and thus which version we can use.

I'm not trying to "handwave."  I'm just repeating to you what I've been told and the reasons for it.  I understand that you disagree with those reasons, but IANAL and am not qualified to respond to these points in detail on behalf of Apple.  I wish I could give you the answers you seek, but that kind of statement is well above my pay grade.
