Clang 15 at least with my build configuration emits warnings about function prototypes that lack argument types. Most notably this happens with functions that take no arguments which in compiler view equates to the void type i.e. void f(void) instead of void f(). As I understand, this will become an error in some future Clang release, so might as well fix it now. Since these were discovered not by a linter but by the actual compiler for my particular build configuration, some f() may have escaped for now. But at least it's enough to build PipeWire with most optional features enabled even when -Werror=strict-prototypes is enabled. For anyone else wanting to have a go at this, these can be upgraded from warnings to errors by adding -Werror=strict-prototypes to the custom CFLAGS which probably works with GCC, too, but has only been done with Clang 15.0.2. Finally my editor automatically stripped trailing spaces upon saving the modified files. I assume it's probably not worth keeping those invisible bytes around but this may have slightly dubious implications as it did also turn indented empty lines of JACK license header into regular empty lines.
