Argh, there's egg on my face: the above is false. -MM can't be
combined (usefully) with -c; it's the -MMD option which can.

Here's a correct, *tested* makefile:
--------
.PHONY: all clean
SRC = main.cpp
COMPILE.cpp += -MMD -MP
all: main.exe
main.exe : main.o
$(LINK.cpp) $< $(LOADLIBES) $(LDLIBS) -o $@
-include $(SRC:.cpp=.d)
clean:
@$(RM) *.o *.exe *.d
--------
Note the use of LINK.cpp to guarantee linking happens with the correct
compilation driver and options.
