Redefinition of function. When the macro OLDER_VERSION_OF_X is enabled, the following compilation error occurs. debianutils/start_stop_daemon.c:194:12: error: redefinition of ‘pid_is_exec’ static int pid_is_exec(pid_t pid) ^ debianutils/start_stop_daemon.c:179:12: note: previous definition of ‘pid_is_exec’ was here static int pid_is_exec(pid_t pid) ^
fixed in git, thanks
