Well, install Linux, first of all it has shared libraries, 2nd is has
a sane filesystem, which means that you are wasting less space on
half-used clusters. And it runs DOOM, not much more to ask for is there.

A bit more serious, the reason why djgpp programs have more overhead
is probably among other things that is has a very versatile wildcard
matching (I'd like to see a MSC program to implement something like
{src,include}/*.[ch], that would also take up space) and protected
more runtime support which means less headache when writing programs.
The obvious solution for this would be shared libraries which are not
feasible for a couple of reasons discussed at length in the past.
