Compiling is completely broken with latest GCC 12.1.0 on Arch Linux and likely others.

I have been making use of osk-sdl on few tablets I have running Arch Linux. I noticed trying to set up osk-sdl on a new tablet it would fail in compiling and then testing it again it would fail to compile on all of my tablets. I'm not exactly sure what changed but when I tried looking up the error messages I got below I found I needed to add #include <array> to the list of 'includes' in the 'keyboard.h' file.
