GCC 14 newly by default treats as errors a number of situations which
before were only warnings.  For more information see
https://gcc.gnu.org/gcc-14/porting_to.html and meta bug #1220571.

Because of this, package ldns fails to compile.  This can be seen online
at:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/ldns/standard/x86_64

It can be reproduced locally with command: osc build --clean
--alternative-project home:rguenther:nextgcc

According to notes from Fedora at
https://gitlab.com/fweimer-rh/fedora-modernc/-/blob/main/pkg/l/ldns.md?ref_type=heads
the related upstream issues seem to be
https://github.com/NLnetLabs/ldns/pull/232 and
https://github.com/NLnetLabs/ldns/pull/233
and Fedora fix seems to be https://src.fedoraproject.org/rpms/ldns/c/15dbd0729dcc0b9ec083def611e11472bc4caff1?branch=rawhide


The first error (that halts the build) is:
