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 libcaca fails to compile. This can be seen online
at:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/libcaca/standard/x86_64
It can be reproduced locally with command: osc build --clean
--alternative-project home:rguenther:nextgcc
We seem to need a patch from
https://src.fedoraproject.org/rpms/libcaca/c/27b246122bf1aa47ab437d09d9a1bdbef64a4b25?branch=rawhide
The (first) error (that halts the build) is:
