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

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

The error (that halts the build) is:


[   79s] tbl.c:173:15: error: assignment to ‘char *’ from incompatible pointer
type ‘char (*)[1]’ [-Wincompatible-pointer-types]
[   79s]   173 |             s = &cp[i].u.s;
