Why is not changing the XFree86-aoutlibs port to offer libs built on
2.2.x not the right fix?

I am very uncomfortable putting in a ld.so built on 3.0 into the compat2?
dists. I'm painfully aware of all the un-thought of issues that can come
up when changing dynamic linking methods, etc.. just look at the two
opposing threads in the past month about how to handle libcc and dynamic
[and threaded] libs and binaries.

Fine BUT IT ISN'T compat2?. PLEASE think about the issues for a moment.
You are mixing bits that are not consistent. Maybe it fixes this one
case, but what about all the other cases. What we need to do is offer
a.out bits so users can duplicate the system the binary was built on.
4.2 a.out bits != 2.2.x a.out bits. There are two issues here -- binary
format (a.out vs. ELF), _and_ library versions.

And is consistent with the binaries and libs of that release.

I'm sure they don't -- I just wrote above I didn't add ld.so to the
compat2? dists until 3.2 and 3.3. So of course the 3.0 and 3.1 a.out
bits are different.

No, you're missing the fact that these are comat2? bits, not a.out bits.
If you want 3.x a.out bits then a compat3x.aout dist should be created.
