Hi all,

Alpine edge now upgraded to GCC 15 as part of the roadmap for Alpine
3.23.

Probably the most disruptive change is the default C language to
-std=gnu23. See <https://gcc.gnu.org/gcc-15/changes.html> and
<https://gcc.gnu.org/gcc-15/porting_to.html>.

Help fixing all the packages now failing with GCC 15 is very welcome,
for that please take a look at the list at
<https://gitlab.alpinelinux.org/alpine/aports/-/work_items/17311>.
