Also "gmake -r" will disable builtin rules.

The builtin rule for checking things out of source uses the "+" prefix
character.  You can find the builtin rules with the -p option, something
like this:

    $ make -pf /dev/null
        ...
    # default
    CHECKOUT,v = +$(if $(wildcard $@),,$(CO) $(COFLAGS) $< $@)
        ...
    %:: RCS/%,v
    #  commands to execute (built-in):
            $(CHECKOUT,v)

The "+" token tells GNU make to run this command line even if -n is
given.
