I would do it with this:
%.o %.h: %.src
cmd $< -o ${@:.h=.o} -h ${@:.o=.h}
The odd address@hidden bits are so that the proper files are generated
regardless of whether make hits this with, for example, "foo.o" as the
target or "foo.h" as the target. Since it bases them off of $@ and
not $<, it'll also work properly with VPATH.
