Dear maintainer(s),
innduct fails to build from source with glibc 2.43, currently in
experimental. From the build log:
| gcc -DHAVE_CONFIG_H -I. -I/usr/include/inn -Wdate-time -D_FORTIFY_SOURCE=2 -Wall -Wformat=2 -Wno-format-zero-length -Wshadow -Wpointer-arith -Wbad-function-cast -Wwrite-strings -Wsign-compare -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wmissing-format-attribute -Wredundant-decls -Wnested-externs -Wno-pointer-sign -Werror -g -O2 -Werror=implicit-function-declaration -ffile-prefix-map=/build/reproducible-path/innduct-2.2=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -mbranch-protection=standard -c -o statemc.o statemc.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.

Aurelien
