The more useful test is how much additional space is taken up incrementally
as you add new code. The baseline size doesn't tell you much except that
the I/O facility takes about 190k. This is not a function so much of the
language as it is of the granularity of the library that gets linked in.

When I compiled your sample with /MD the executable was only 3,584 bytes.
This tells the compiler not to statically link the runtime library, but to
use msvcrt dll instead. I also specified /O1 which is optimize for size.
