It is the statically linked C library. Note that if you remove
the call to printf, the size is slashed in half.
Windows traditionally didn't do a system-wide C lib, but rather
the various compiler vendors would do their own. To keep this
from being a big pain for the end user, static linking can be
employed as it apparently is with Digital Mars.

I'm not 100% sure this is the same, but I suspect it probably
is.
.. on freebsd ..

If you ldd that, you'll see it dynamically links the C library.
The downside of this is there's less binary compatibility
across major versions; you are liable to need to recompile from
source to deal with different libc versions on the system,
whereas the Windows builds are more likely to just work.
There is system-wide C library. It is named msvc.dll.
TCC uses it producing very small executables.
