Dear maintainer(s),
gcl fails to build from source with glibc 2.43, currently in
experimental. From the build log:
| gcc -c -g -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/gcl-2.6.14=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -mbranch-protection=standard -fsigned-char -pipe -fcommon -fno-builtin-malloc -fno-builtin-free -fno-PIE -fno-pie -fno-PIC -fno-pic -std=gnu17 -Wall -Wno-empty-body -Wno-unused-but-set-variable -Wno-tautological-compare -I/usr/include/tirpc -Wdate-time -D_FORTIFY_SOURCE=2 -O2 -I/build/reproducible-path/gcl-2.6.14/o -I../h -I../gcl-tk number.c

The full build log is available here [1].
The issue is due to ISO C23 declaration of bsearch, memchr, strchr,
strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr,
which now returns a pointer to a const-qualified type when the input
argument is a pointer to a const-qualified type [2].
I would like to thanks Emanuele Rocca for doing the archive rebuild on
a fast arm64 server.
Regards
Aurelien
