Correcting myself. This has the disadvantage of re-calculating *all*
rules if *one* source-file chagnes. You could do better (recalculate
only the relevant rules) like this: ::
SRCS := s1.c s2.c ... sN.c
%.mk : %.c
write_rule $< >> $@
include $(SRCS:.c=.mk)
This will of-course create many "autogenerted" makefiles, one for
every source-file, which will all get included.
