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

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

Fedora dealt with these issues as described at
https://gitlab.com/fweimer-rh/fedora-modernc/-/blob/main/pkg/h/hplip.md?ref_type=heads
We seem to need at least https://bugs.launchpad.net/hplip/+bug/1997875
and https://bugs.launchpad.net/hplip/+bug/2048780

The error (that halts the build) is:

[   31s] prnt/hpps/pserror.c: In function ‘message’:
[   31s] prnt/hpps/pserror.c:27:10: error: type defaults to ‘int’ in
declaration of ‘column’ [-Wimplicit-int]
[   31s]    27 |   static column = 0 ;           /* current screen column for
message wrap */
