Whoah. So my assumption in
<CACBZZX78oKU5HuBEqb9qLy7--wcwhC_mW6x7Q+tB4suxohSCsQ@xxxxxxxxxxxxxx>
that nobody was compiling this & thus not reporting failures was
false. Rather there's an entire community & distribution mechanism
around patching git for older EL versions, but the patches aren't
making it upstream.

It would be great to have them on-list, as far as I can tell they were
never submitted? Is there some time/administrative reason for why
you're not submitting them? Some of these are many years old, it would
be great to have them on-list for wider review & included so vanilla
git works on these platforms.
