Compilation errors on Linux

Issue

I am trying to compile osrm-backend on Arch Linux with gcc 14.1.1. I checked out the latest git master branch, commit 21607e0cb2e8446f9c2a18dfbff08fba02dfa1d8.

The compilation fails with

In file included from [...]/osrm-backend/include/util/timezones.hpp:10,
                 from [...]/osrm-backend/src/util/timezones.cpp:1:

Steps to reproduce

Compile with

$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .
