Only if the Makefile has been written with parallel execution in mind - it's very easy to produce rules which have hidden dependencies encoded in the order of the prerequisites (and which can be darned hard to debug...). Personally, I'd never assume that a Makefile will automatically work with -j (though I do agree that build systems should be written for parallel execution from day 0).

What do you mean by phasing out ocamldep? An alternate tool, handwritten dependencies (ouch) or something more complex?
