========================
-d Generate dependency information

	If file.c is being compiled, then file.dep will be created.
	It will contain a list of #include files that file.obj depends
	on. So, the line in the makefile can be written as:

	file.obj : $(file.dep) file.c
	    sc -c file -d
========================

How can I use -d with implicit rules e.g. :
c.obj::
   $(CPP) $(CPP_OPTS) $<

???

I mean, I would like to simplify huge makefiles full of :

..
SOURCE=..\..\Src\Audio\SDL_audiocvt.c
DEP_CPP_SDL_AUD=\
	"..\..\include\begin_code.h"\
	"..\..\include\close_code.h"\
	"..\..\include\sdl_audio.h"\
	"..\..\include\sdl_byteorder.h"\
	"..\..\include\sdl_error.h"\
	"..\..\include\sdl_main.h"\
	"..\..\include\sdl_rwops.h"\
	"..\..\include\sdl_types.h"\
	

"$(INTDIR)\SDL_audiocvt.obj" : $(SOURCE) $(DEP_CPP_SDL_AUD) "$(INTDIR)"
	$(CPP) $(CPP_PROJ) $(SOURCE)
..

is the simplest form :

SOURCE=..\..\Src\Audio\SDL_audiocvt.c

"$(INTDIR)\SDL_audiocvt.obj" : $(SOURCE) $*.dep "$(INTDIR)"
	$(CPP) $(CPP_PROJ) $(SOURCE)
???

The sc -d does not indicate where is put the generated .dep file.
It is in the directory where the makefile is run.
(Should not that be documented ?, and/or it should possible to
indicate where the file is to be put ? (default: with the .c ?))

TIA

There also is a separate utility by the name of makedep that does this for
you.
I have a modified version of makedep.exe named DEP.EXE for Win32 at:
ftp://ftp.janknepper.com/Win32/DEP.EXE
