I finally got everything working (seems to do the right thing in all cases). 
One thing I had to do was change the rules to do

        %.css  --> %.o
        %.png  --> %.o
        %.html --> %.o

Instead of what I would've preferred:

        %.css  --> %.css.o
        %.png  --> %.png.o
        %.html --> %.html.o

That took care of not only the circular dependency, but the occasional tendency 
for Make to do the reverse of creating a .o from a .html: it would overwrite 
the .html from the .o!

Thanks for your help.
