.c.s: in linux-0.11 makefile

I have tried to build linux-0.11. And I found that the makefile in linux-0.11 contains :

.c.s:
@$(CC) $(CFLAGS) -S -o $*.s $<
.s.o:
@$(AS) -o $*.o $<
.c.o:
@$(CC) $(CFLAGS) -c -o $*.o $<

Could anyone tell me that what does .c.s:, .s.o: and .c.s: mean?

Thanks!

Those are suffix rules. They are a more primitive and limited (but standards conforming) form of pattern rules.

The rule .c.o means "if you have a foo.c, you can turn it into a foo.o with this recipe". Ditto for the others.
