Squelch "passing arguments to 'xxxxx' without a prototype is
deprecated in all versions of C and is not supported in C2x" error
thrown by Apple clang version 14.0.3 (clang-1403.0.22.14.1) (Xcode 14.3).

In this instance, passing the argument is incorrect, since UNLSN() and
UNTLK() don't actually take one.
