I've seen them, but I am on vacation with limited connectivity so I can't

I thought this allowed you to do:


.SUFFIXES: .gz

.NULL.gz:  
        gzip ${.ALLSRC}

all: foo.gz

but I see it does not work. But if you remove .NULL, how can you make it
work? I think that the most important feature missing in make is pattern
rules; the whole suffix thing should be scrapped and implemented in terms
of pattern rules. But that's a larger project.
