If you don't know *exactly* why it doesn't build, I don't think you
should be blaming us for it. (FWIW, I just tried to build 7.1 branch
on RHL 8.0 --- the main problem seems to be that 7.1's configure isn't
expecting multiline output from "gcc --version", and it produces a
PG_VERSION_STR definition that's missing a trailing quote. There are
some other issues, none that look very difficult to fix, all indicative
of incompatible changes in either gcc or system include files.)

Oh? Do they have a crystal ball that lets them predict incompatible
future platform changes?
(I'm not very sure I believe your assertion above, anyway. We are
painfully aware of our own compatibility issues, but I wonder how many
people on this list pay close enough attention to MySQL to know what
their version-to-version compatibility track record *really* is.)

You could do so if you were willing to track the platform changes.
7.1 isn't hopelessly broken for RHL 8.0, but it's definitely suffering
bit rot. Someone would have to expend effort on updating obsolete
branches, if we wanted them to keep working in the face of incompatible

Well, this is exactly the issue: someone would have to put substantial
amounts of time into update mechanisms and/or maintenance of obsolete
versions, as opposed to features, performance improvements, or bug
Personally, I feel that if we weren't working as hard as we could on
features/performance/bugfixes, the upgrade issue would be moot because
there wouldn't *be* any reason to upgrade. So I'm not planning to
redirect my priorities. But this is an open source project and every
developer gets to set their own priorities. If you can persuade someone
to put their time into that, go for it.

I think you're wasting your time trying to hold us to a higher standard
of backwards-compatibility than is maintained by the OSes and tools we
must sit on top of.
