If you're using checked-out source, then automake should have
created an appopriate Makefile.in that has this clause in it:

%.o: %.c
        @echo '$(COMPILE) -c $<'; \
        $(COMPILE) -Wp,-MD,.deps/$(*F).pp -c $<
        @-cp .deps/$(*F).pp .deps/$(*F).P; \
        tr ' ' '\012' < .deps/$(*F).pp \
          | sed -e 's/^\\$$//' -e '/^$$/ d' -e '/:$$/ d' -e 's/$$/ :/' \
            >> .deps/$(*F).P; \
        rm .deps/$(*F).pp

Notice the -Wp,-MD option to $(COMPILE). 'automake' is run when
initializing your checked-out source via './autogen.sh'

When packing the source for a distribution via 'make dist', this
auto-generation of dependencies is removed, and the dependencies themselves
are put into Makefile.in.
