Thanks for the patch. I've applied it to a temporary git branch for
now, see below. Since the previous upload (1.0.4-1 in 2023-06) two
unrelated bugs have been found and fixed, so it would be good to get
these in as well. Do you want me to adjust the debian/changelog to
mention these fixes before merging the temporary branch?

No concerns but some questions:
* The tfortune package depends on liblopsub and currently has
Depends: ${shlibs:Depends}, liblopsub1, ${misc:Depends}
in its own debian/control file. When would be the best time to replace
liblopsub1 by liblopsub1t64?
* Why did you call the new version 1.0.4-1.1? Why not 1.0.5-1 instead?
* Do I need to do anything else to get this going besides merging
the branch and pushing it to the public repo?
Thanks
Andre

commit 806c7a89423cf70c1593325de24be0b160ffde96

64-bit time_t transition.
As part of the 64-bit time_t transition required
to support 32-bit architectures in 2038 and beyond
(https://wiki.debian.org/ReleaseGoals/64bit-time), we have identified
liblopsub as a source package shipping runtime libraries whose ABI
either is affected by the change in size of time_t, or could not be
analyzed via abi-compliance-checker (and therefore to be on the safe
side we assume is affected).
To ensure that inconsistent combinations of libraries with their
reverse-dependencies are never installed together, it is necessary
to have a library transition, which is most easily done by renaming
the runtime library package.
Since turning on 64-bit time_t is being handled
centrally through a change to the default dpkg-buildflags
(https://bugs.debian.org/1037136), it is important that libraries
affected by this ABI change all be uploaded close together in time.
Therefore I have prepared a 0-day NMU for liblopsub which will
initially be uploaded to experimental if possible, then to unstable
after packages have cleared binary NEW.
