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.
