What about doing something evil like:

    foo.sentinel:
        touch $@

    FOO_MAKER = $(shell touch foo.sentinel)

    foo:

    bar: _DUMMY := $(FOO_MAKER)
    bar: foo foo.sentinel
        @echo Making $@

Basically I've stuck the foo-maker target inside a target specific
variable for bar which means that it'll get run before bar's targets.

John.
