-Unboxed (Compiler must place on pointer stack not data stack
-	 Must also tell GC if it is in a register when GC invoked)

-Info1:
-	SPEC_INFO_TABLE(Info1, BigNum_entry, 1, 1);	(Min Size 2 ?)
-
-	Entering this returns the BigNum using agreed return convention
-
-Info2:
-	DATA_INFO_TABLE(Info2, Dummy_entry);
-
-	This never actually entered -- just required for GC.

-(unboxing represents evaluationhood, not pointerhood)
