Almost.  It looks like -MMD disables this behaviour so now that particular test
fails in the opposite way.

$ gcc-4.8.0 -c -Wp,-MD,expected.d test.c && cat expected.d 
test.o: test.c /usr/include/stdc-predef.h test1.h test3.h test2.h

$ gcc-4.8.0 -c -Wp,-MMD,expected.d test.c && cat expected.d 
test.o: test.c test1.h test3.h test2.h
