Check <sys/cdefs.h>..  For gcc-2.7.x and above, it's a
#define __unused __attribute__((__unused__))
For everything else, it does nothing.  It should not be a portability
issue, since we compile the kernel with -Wunused on gcc, and it's telling
us exactly what we asked for..  Unused variables..

Cheers,
