Now that the rule is right:

	%-A4.tex-ps: %.sgml $(ALLSGML) stylesheet.dsl bookindex.sgml
	        $(JADE.tex.call) -V texdvi-output -V '%paper-type%'=A4 -o $@ $<
	ifndef DRAFT
	        @cmp -s HTML.index.start HTML.index || $(MAKE) $@
	endif

The rule re-runs the makefile for the specific target, and the target
modifies HTML.index, or it is only the HTML rule that modifies that.
That was a question I had.  If that is true, it has to be:

	%-A4.tex-ps: %.sgml $(ALLSGML) stylesheet.dsl bookindex.sgml
	        $(JADE.tex.call) -V texdvi-output -V '%paper-type%'=A4 -o $@ $<
	ifndef DRAFT
	        @cmp -s HTML.index.start HTML.index || $(MAKE) html $@
	endif
