Subject: [PATCH] More cases of #5477 functions with empty argument lists

Building on macOS 13.3.1 (22E261) clang 14.0.3 (clang-1403.0.22.14.1)
running to errors like #5477 where functions without argument lists at
least need void.

Looking for possible suspect functions via:

  git grep -E "^([A-Za-z_]+ )?[A-Za-z_]+\()" \*.c \*.m
