Doesn't compile on Arch

I get the following compiler error:

Looks like this is a problem in SDL. I'll follow up there.

Found it: https://github.com/libsdl-org/SDL/issues/5535

Ultimately it is a problem in PipeWire, which is fixed. I simply applied the small change to my string.h include file and it compiles. https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2303

Linux is not officially supported. You may be able to find help on the community discord Gyro Gaming. If you do find a fix, feel free to suggest a pull request and I will merge it.
