Some of it exists but I don't think its complete.

Hmm, I don't think so.  Which makefile did you add this to?  Are
you using the new makefile?  The Makefile.pre.in file contains a
line like:

    $(LIBRARY_OBJS) $(MAINOBJ): $(PYTHON_HEADERS)

but newmodule.o not in LIBRARY_OBJS.  By default its not compiled
by make but with distutils.  If you add newmodule to Setup then a
line like:

    Modules/newmodule.o: $(PYTHON_HEADERS)

would do the trick.  I think I will add a line like:

    $(MODOBJS): $(PYTHON_HEADERS)

to fix the problem.

I could easily restore the mkdep target but my feeling right now
that explicitly including the header dependencies is better.
What do you think?
