Dear maintainer(s),
tuxpaint fails to build from source with glibc 2.43, currently in
experimental. From the build log:
| src/i18n.c: In function ‘set_current_language’:
| src/i18n.c:1239:37: error: assignment of read-only location ‘*(const char *)strchr(short_lang_prefix, 95)’

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
