I'm kinda partial to

#define major(a) @@BOGON@@

which is pretty much guaranteed to give you an error on expantion :-)

or any of a dozen variations I've seen over the years:

#define major(a) TriplePlusUngood
#define major(a) *BoGoN++
#define major(a) { int i; void *j; j = i; }

(although the latter isn't effective on some compilers)
