I use a special pair of rules to autogenerate dependencies.  A "pair" because there are two separate stages -- "gcc -MM" and "sed s/.../.../", and each can generate an error.

This is done with following rules (gcc>2.95, due to "-MF"):

%.d: %.dep
sed   's/$*.o :/$.o $@:/' <$*.dep >$@
%.dep: %.c
$(CC)   -MM $(CPPFLAGS) $< -MF$@ >/dev/null

and "include $(ALLDEPENDS)" where ALLDEPENDS contains list of all .d-files.

Everything is fine -- make regenerates these .d-files upon change of .c or any of included files, and automatically removes intermediate .dep-files.

BUT: when running with "-n" switch, make still performs this .c->.dep->.d sequence (since otherwise it wouldn't be able to have an up-to-date makefile), but DOES NOT remove .dep-files.  So that they remain sitting there forever.

(BTW, does Savannah registration work? It tells "You are now being sent a confirmation email", but that email never reaches me...)
