Hi Martin,

the utility gm2m probably will help, if run with -depends it should
emit a dependency graph in Makefile format.
So for example:

$HOME/opt/bin/gm2m -depend Map.mod 
Map: Map.o RoomMap.o Geometry.o Chance.o StoreCoords.o BoxMap.o  \
     MakeBoxes.o WriteMap.o RoomMap.def WriteMap.def
Map.o: Map.mod RoomMap.def WriteMap.def
Map.mod: RoomMap.def WriteMap.def
RoomMap.o: RoomMap.def RoomMap.mod Geometry.def Chance.def  \
           StoreCoords.def BoxMap.def
RoomMap.mod: RoomMap.def Geometry.def Chance.def StoreCoords.def  \
             BoxMap.def
Geometry.o: Geometry.def Geometry.mod
Geometry.mod: Geometry.def
Chance.o: Chance.def Chance.mod
Chance.mod: Chance.def
StoreCoords.o: StoreCoords.def Chance.def StoreCoords.mod
StoreCoords.mod: StoreCoords.def Chance.def
BoxMap.o: BoxMap.def Geometry.def StoreCoords.def Chance.def  \
          BoxMap.mod MakeBoxes.def
BoxMap.mod: BoxMap.def Geometry.def MakeBoxes.def StoreCoords.def  \
            Chance.def
MakeBoxes.o: MakeBoxes.def Chance.def MakeBoxes.mod
MakeBoxes.mod: MakeBoxes.def Chance.def
WriteMap.o: WriteMap.def RoomMap.def WriteMap.mod
WriteMap.mod: WriteMap.def RoomMap.def

you should be able to include this into a Makefile which I think will
achieve what you desire?
