	In many cases, the compiler won't COMPILE.  There will be places that
	access the operator optables without a HAVE_xxxx guard.

	I know for a fact that the compiler won't compile without one of the shift operators, (arithmetic
	right shift, if I remember correctly).

	I also doubt the compiler will work if there's not an addM3 pattern, for at least some mode.
