It's not harder provided our <sys/cdefs.h> is included.  __unused
is a macro.

It is harder if you don't control the system headers.  Have a look
at the lbl stuff in contrib.  Each module now carries its own
definitions of __dead and __attribute in case the system doesn't
define them.  __dead still works for it here although I removed
__dead from my <sys/cdefs.h>.
