1) Jul 4th. The optimizer attempted to cnvert:
	movb	x,y
	tst	y
to:
	movb	x,y
	(condition codes implicitly set)

The obvious change is emembering the sense of the last
instruction which set the condition codes (byte
or word).

2) To conform with the new manual, initializers may be introduced
by "=".

3) Register count properly restored on exiting block.
