Steps to reproduce the problem
Build kamailio phonenum module on Fedora 39
https://github.com/kamailio/kamailio/tree/master/src/modules/phonenum
What version of Abseil are you using?
abseil-cpp-20230802.1-1.fc39.x86_64
abseil-cpp-testing-20230802.1-1.fc39.x86_64
abseil-cpp-devel-20230802.1-1.fc39.x86_64
What operating system and version are you using?
Fedora 39
What compiler and version are you using?
clang-resource-filesystem-17.0.4-1.fc39.noarch
clang-libs-17.0.4-1.fc39.x86_64
clang-17.0.4-1.fc39.x86_64
```
### What build system are you using?
To bulid Kamailio used Makefiles
### Additional context
The same module compiled properly on Fedora 38.
A probable issue happens after devel files update.

From your log:
clang -std=c++11
...
79 | #error "C++ versions less than C++14 are not supported."
| ^
You are trying to build in C++11 mode when you need at least C++14.

Thanks @derekmauro, I have used -std=c++17 and this solved program build.
