Well I have a post to debian-devel-announce today which would've provided
more pointers to this sort of thing, but unfortunately lists.debian.org no
longer appears to reliably let mail through from Debian Developers (despite
having valid signatures with both dkim and PGP).

libnma falls into the bucket of packages that we weren't able to analyze, so
we assume out of an abundance of caution that it is ABI-breaking and should
be renamed:

  https://adrien.dcln.fr/misc/armhf-time_t/2024-02-01T09%3A53%3A00/logs/libnma-headers/base/log.txt

If you feel strongly that the package should not be renamed, patches to
https://salsa.debian.org/vorlon/armhf-time_t/-/blob/main/check-armhf-time_t?ref_type=heads
are very welcome to make it possible to compile the headers for analysis and
confirm that the library's ABI is not affected by time_t.

From the log it looks like this is a missing gtk include, which can easily
be fixed either in the upstream source or by adding an appropriate quirk to
the above script.

We will happily rerun abi-compliance-checker to confirm the ABI status if
this is fixed.

Thanks,
