+ *		This module only exists because I don't know how to get the silly C compiler
+ *		and/or linker to generate data areas that are aligned on a particular boundary.
+ *		And, this stuff is in the V=R mapped area.
+ *
+ *		Do the following for each:
+ *
+ *				.size	name,size-in-bytes
+ *				.type	area-name,@object
+ *				.globl	area-name
+ *				.align 	power-of-two
+ *		area-name:
+ *				.set	.,.+size-in-bytes
+ *
+ *		So long as I'm being pedantic, always make sure that the most aligned,
+ *		i.e., the largest power-of-twos, are first and then descend to the smallest.
+ *		If you don't, and you are not careful and hand calculate, you'll end up
+ *		with holes and waste storage.  I hate C.
+ *
+ *		Define the sizes in genassym.c
