I don't recommend this, actually: to be more correct you should use:
CPP = gcc -E
Then something like:
COMPILE.i = $(CPP) $(CPPFLAGS) -o $@
%.i : %.c
$(COMPILE.i) $<
%.i : %.cc
$(COMPILE.i) $<
The -E flag is what tells "gcc" to stop after the preprocessing stage,
and so it more correctly belongs directly in the CPP macro. If you were
using a different preprocessor, like "cpp" directly, you would want to
replace the entire thing and not have the extra "-E" lying around.
