Description Martin Jambor 2024-06-04 11:50:54 UTC 
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 rubygem-rdiscount fails to compile.  This can be seen online
at:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/rubygem-rdiscount/standard/x86_64

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


The (first) error (that halts the build) is:

[    9s] gethopt.c:48:1: error: type of ‘val’ defaults to ‘int’ [-Wimplicit-int]
[    9s] gethopt.c: In function ‘gethopt’:
[    9s] gethopt.c:59:1: warning: old-style function definition [-Wold-style-definition]
[    9s]    59 | gethopt(ctx, opts, nropts)
[    9s]       | ^~~~~~~
