BTW defined (__i386__) or defined __i386__ .

http://www.gnu.org/prep/standards/standards.html#Comments

Therefore:
#if defined __i386__ || defined __x86_64__

but then negative:

#else /* !defined __i386__ && !defined __x86_64__ */
#endif /* !defined __i386__ && !defined __x86_64__ */

(+cpuid comments in other mails)
