Problems with recompiling, when changing header files in C

I have the following problem, when I compile a C Program:

I create dependencies using .d files automatically uisng the gcc -M feature
I include the so created .d files using:
        -include $(C_SRC_FILES:.c=.d)
        -include $(ASS_SRC_FILES:.ss=.d)


Then if I change one of the c files everything works great. 
BUT if I change one of the header files, nothing gets recompiled !!!!!

One of the .d files looks for example like this:
- -------------------
modTask.o modTask.d : aufsicht/modTask.c \
 include/hwdefs.h 
- -------------------
If I change the file include/hwdefs.h, NOTHING gets recompiled !!!!

I use rules like:
- ----------------
## Rules to make the object files
##
%.o : %.c $(ALL_MAKEFILES) 
        @echo " **** Compiling file $< "
        $(CC) -c $(CFLAGS) $< -o $(OBJECT_DIR)/$(notdir $@)

%.o : %.ss $(ALL_MAKEFILES)
        @echo " **** Compiling file $< "
        $(CC) -c $(CFLAGS) $< -o $(OBJECT_DIR)/$(notdir $@)
- -----------------------


Can somebody tell me my mistake ???
Thank you very much !!!
