This is necessary in order to build with C23, which is the default standard in GCC 15. In C23, `int foo()` is no longer a function taking unspecified arguments, but a function taking no arguments, like `int foo(void)`. Furthermore, treating a pointer to a function of unspecified arguments as compatible with a pointer to a function with declared arguments was probably always dubious, although it worked in practice.
