I have upgraded fedora's buildbot to fedora 30 that comes with

clang version 8.0.0
Those give quite a few new warnings.
See:

and

I am not sure how serious are those, perhaps somebody more qualified can
have a look.
I pushed the following change on default:
http://hg.savannah.gnu.org/hgweb/octave/rev/fc256e9d882e
This change eliminates many warnings in Octave for me with GCC 9 but
there are still many others due to similar issues in Qt class declarations.
It does not fix problems found with clang due to
-Wdefaulted-function-deleted. I'll try to take a look at that as well.
