: gcc has a much more powerful feature.  In your Makefile, add the "-MD"
: or "-MMD" options to gcc.  Then, add this at the end of your Makefile:

: 	DEPS := $(wildcard *.d)
: 	ifneq ($(DEPS),)
: 	include $(DEPS)
: 	endif

: gcc will automatically generate dependencies as it compiles, and make
: will automatically use any that gcc has generated.  This is much more
: reliable than using makedepend.

But requires you to run make twice to be sure everything is built.

How about adding something like this too?

  ifeq ($(SECOND_RUN),)
  make SECOND_RUN=1
  endif
