This feature was intentionally removed after 3.76.1 as it caused too
many problems.
You'll have to either stick with 3.76.1, or fix your makefile.
ml> .PHONY : default all depend
ml> depend :
ml> $(DEPEND): depend
ml> @echo "Updating dependencies ..."
ml> @$(CXX) -MM $(CXXFLAGS) $(SRCS) | sed 's|\w*\.o|$(LIB)(&)|' > $(DEPEND)
ml> @$(CXX) -MM $(CXXFLAGS) $(PRGS) >> $(DEPEND)
ml> -include $(DEPEND)
This sequence is your problem: you define "depend" to be .PHONY, so it's
always out of date, then you define $(DEPEND) to depend on it, so
$(DEPEND) is always considered out of date.
You should have $(DEPEND) depend on the source files, etc., directly
rather than on a .PHONY target. That way it's only rebuilt if one of
the source files changes.
You might also want to take a look on my web site below for a more
advanced way of doing automated dependency maintenance.
