No I didn't upgrade / downgrade libncurses-devel concurrently with libreadline-devel.
In fact after upgrading back to 8.2-2 and confirming the failed build I retained all current and up-to-date
and made _just_one_change_: I extracted the single file libreadline.a from libreadline-devel-8.1-2.tar.xz
(i.e. just one reversion to 8.1 not two to 7.0) and substituted it in place leaving everything else as for 8.2-2
including libreadline.dll.a and confirmed that this single substitution allowed the build. 

I suppress the warnings because there are so many of them! I can supply them but for the moment the issues
that prevent a successful build using libreadline.a (8.2-2) are listed in the attached text file.

Thank you very much for taking an interest.
