False positives for unusedFunction in Myrlyn

[Christoph]

Dear cppcheck team!

I used Cppcheck on Myrlyn [1]. It reports dozens of unused functions. I
checked several of them and only found false positives.

Example:

/home/gruenich/myrlyn/src/YQZypp.h:84:0: style: The function 'ZyppRepositoriesEnd' is never used. [unusedFunction]
inline ZyppRepositoryIterator ZyppRepositoriesEnd() { return zyppPool().knownRepositoriesEnd(); }
^

Removing the function leads to a compiler error that the function is
missing. A simple git grep finds multiple uses of the function.

What can I provide to help you identify the problem within Cppcheck? I
use Cppcheck 2.17.0. The command I executed was:

cppcheck --std=c++17 --check-level=exhaustive --project=compile_commands.json --enable=all --suppress=missingIncludeSystem

Can you provide a reduced, self-contained example that shows the issue?
