Ah yes, you do need all the other programs. Nevertheless, "all" the
other programs is still likely to be a short list, perhaps 20 or so.
Each of these is likely a single executable, and you might have to do
something about the standard C library. It should be nothing like
trying to get gcc installed with its zillions of files.


DOS batch files always struck me as disappointingly weak, though I
can't remember the specific reasons why. They are okay for running a
command or two, but they are much worse than Unix shell scripts once
you start doing subroutines and loops and such. If one were to
rewrite a Unix script to run on DOS, I would think it easier to use
almost any language, even C.
