Dear maintainer(s),

procenv fails to build from source with glibc 2.43, currently in
experimental. From the build log:

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

Hi,

With the upload of glibc 2.43 to unstable, the packages now FTBFS in
unstable, hence upgrading the severity to serious.

Note that as a quick workaround, it is possible to roll back to C/C++17
standard using -std=c17, -std=gnu17, std=c++17 or std=gnu++17. This was
the default up to GCC 14, and GCC 15 changed it to C/C23.

Regards
Aurelien

Debdiff attached and uploaded.
I also improved a little bit the packaging.
