#7 .depend file in 0.9 tarball should be removed

[David M. Cooke]

The .depend file in the cf-0.9 tarball shouldn't be included, as it's machine-specific (the absolute paths to the OCaml header files are included).

Also, I'd suggest that the rule

$(DEPEND_FILE) ::

be a single-colon definition so that 'make' will actually remake it automatically (see the `Remaking Makefiles' node in the GNU make manual for why double-colon targets for included makefiles don't remake the file). Adding a clean:: action to remove the .depend wouldn't hurt either.

Otherwise, a very clean Makefile :)
