Future releases of GCC will render function definitions like
func()
invalid by default. See the previous commit 09f88c9 ("Fixed main()
prototypes in auto tests.") for details.
Such functions should be defined like
func(void)
This is a good thing to do regardless of the upcoming GCC changes.

For backward compatibility, the Linux capabilities macros exposes v1 semantics
(32-bit) by default. We probe the version at runtime (because of pre-compiled
binaries) but the kernel syscall API is conservative and it doesn't return a
64-bit capability version if the input version is v1.
This patch suppress the kernel > 5.0 dmesg log below:
capability: warning: 'unitd' uses 32-bit capabilities (legacy support in use)
